Ubuntu Security Notice USN-1551-1
August 30, 2012

thunderbird vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 11.04
- Ubuntu 10.04 LTS

Summary:

Multiple security issues were fixed in Thunderbird.

Software Description:
- thunderbird: Mozilla Open Source mail and newsgroup client

Details:

Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary, Andrew
Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and Daniel
Holbert discovered memory safety issues affecting Thunderbird. If the user
were tricked into opening a specially crafted E-Mail, an attacker could
exploit these to cause a denial of service via application crash, or
potentially execute code with the privileges of the user invoking
Thunderbird. (CVE-2012-1970, CVE-2012-1971)

Abhishek Arya discovered multiple use-after-free vulnerabilities. If the
user were tricked into opening a specially crafted E-Mail, an attacker
could exploit these to cause a denial of service via application crash, or
potentially execute code with the privileges of the user invoking
Thunderbird. (CVE-2012-1972, CVE-2012-1973, CVE-2012-1974, CVE-2012-1975,
CVE-2012-1976, CVE-2012-3956, CVE-2012-3957, CVE-2012-3958, CVE-2012-3959,
CVE-2012-3960, CVE-2012-3961, CVE-2012-3962, CVE-2012-3963, CVE-2012-3964)

Mariusz Mlynsk discovered that it is possible to shadow the location object
using Object.defineProperty. This could potentially result in a cross-site
scripting (XSS) attack against plugins. With cross-site scripting
vulnerabilities, if a user were tricked into viewing a specially crafted
E-Mail, a remote attacker could exploit this to modify the contents or
steal confidential data within the same domain. (CVE-2012-1956)

Fr?d?ric Hoguin discovered that bitmap format images with a negative height
could potentially result in memory corruption. If the user were tricked
into opening a specially crafted image, an attacker could exploit this to
cause a denial of service via application crash, or potentially execute
code with the privileges of the user invoking Thunderbird. (CVE-2012-3966)

It was discovered that Thunderbird's WebGL implementation was vulnerable to
multiple memory safety issues. If the user were tricked into opening a
specially crafted E-Mail, an attacker could exploit these to cause a denial
of service via application crash, or potentially execute code with the
privileges of the user invoking Thunderbird. (CVE-2012-3967, CVE-2012-3968)

Arthur Gerkis discovered multiple memory safety issues in Thunderbird's
Scalable Vector Graphics (SVG) implementation. If the user were tricked
into opening a specially crafted image, an attacker could exploit these to
cause a denial of service via application crash, or potentially execute
code with the privileges of the user invoking Thunderbird. (CVE-2012-3969,
CVE-2012-3970)

Christoph Diehl discovered multiple memory safety issues in the bundled
Graphite 2 library. If the user were tricked into opening a specially
crafted E-Mail, an attacker could exploit these to cause a denial of
service via application crash, or potentially execute code with the
privileges of the user invoking Thunderbird. (CVE-2012-3971)

Nicolas Gr?goire discovered an out-of-bounds read in the format-number
feature of XSLT. This could potentially cause inaccurate formatting of
numbers and information leakage. (CVE-2012-3972)

It was discovered that when the DOMParser is used to parse text/html data
in a Thunderbird extension, linked resources within this HTML data will be
loaded. If the data being parsed in the extension is untrusted, it could
lead to information leakage and potentially be combined with other attacks
to become exploitable. (CVE-2012-3975)

It was discovered that, in some instances, certain security checks in the
location object could be bypassed. This could allow for the loading of
restricted content and can potentially be combined with other issues to
become exploitable. (CVE-2012-3978)

Colby Russell discovered that eval in the web console can execute injected
code with chrome privileges, leading to the running of malicious code in a
privileged context. If the user were tricked into opening a specially
crafted E-Mail, an attacker could exploit this to cause a denial of service
via application crash, or potentially execute code with the privileges of
the user invoking Thunderbird. (CVE-2012-3980)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
thunderbird 15.0+build1-0ubuntu0.12.04.1

Ubuntu 11.10:
thunderbird 15.0+build1-0ubuntu0.11.10.1

==========================================================================
Ubuntu Security Notice USN-1505-2
August 30, 2012

icedtea-web regression
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 11.10
- Ubuntu 11.04

Summary:

USN 1505-1 introduced a regression in the IcedTea-Web Java web browser
plugin that prevented it from working with the Chromium web browser.

Software Description:
- icedtea-web: A web browser plugin to execute Java applets

Details:

USN-1505-1 fixed vulnerabilities in OpenJDK 6. As part of the update,
IcedTea-Web packages were upgraded to a new version. That upgrade
introduced a regression which prevented the IcedTea-Web plugin from
working with the Chromium web browser in Ubuntu 11.04 and Ubuntu 11.10.
This update fixes the problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that multiple flaws existed in the CORBA (Common
Object Request Broker Architecture) implementation in OpenJDK. An
attacker could create a Java application or applet that used these
flaws to bypass Java sandbox restrictions or modify immutable object
data. (CVE-2012-1711, CVE-2012-1719)

It was discovered that multiple flaws existed in the OpenJDK font
manager's layout lookup implementation. A attacker could specially
craft a font file that could cause a denial of service through
crashing the JVM (Java Virtual Machine) or possibly execute arbitrary
code. (CVE-2012-1713)

It was discovered that the SynthLookAndFeel class from Swing in
OpenJDK did not properly prevent access to certain UI elements
from outside the current application context. An attacker could
create a Java application or applet that used this flaw to cause a
denial of service through crashing the JVM or bypass Java sandbox
restrictions. (CVE-2012-1716)

It was discovered that OpenJDK runtime library classes could create
temporary files with insecure permissions. A local attacker could
use this to gain access to sensitive information. (CVE-2012-1717)

It was discovered that OpenJDK did not handle CRLs (Certificate
Revocation Lists) properly. A remote attacker could use this to gain
access to sensitive information. (CVE-2012-1718)

It was discovered that the OpenJDK HotSpot Virtual Machine did not
properly verify the bytecode of the class to be executed. A remote
attacker could create a Java application or applet that used this
to cause a denial of service through crashing the JVM or bypass Java
sandbox restrictions. (CVE-2012-1723, CVE-2012-1725)

It was discovered that the OpenJDK XML (Extensible Markup Language)
parser did not properly handle some XML documents. An attacker could
create an XML document that caused a denial of service in a Java
application or applet parsing the document. (CVE-2012-1724)

As part of this update, the IcedTea web browser applet plugin was
updated for Ubuntu 10.04 LTS, Ubuntu 11.04, and Ubuntu 11.10.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 11.10:
icedtea-6-plugin 1.2-2ubuntu0.11.10.3

Ubuntu 11.04:
icedtea-6-plugin 1.2-2ubuntu0.11.04.3

After a standard system update you need to restart your web browser
to make all the necessary changes.

Summary:

ImageMagick could be made to crash or run programs as your login if it
opened a specially crafted file.

Software Description:
- imagemagick: Image manipulation programs and library

Details:

Tom Lane discovered that ImageMagick would not always properly allocate
memory. If a user or automated system using ImageMagick were tricked into
opening a specially crafted PNG image, an attacker could exploit this to
cause a denial of service or possibly execute code with the privileges of
the user invoking the program.

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
imagemagick 8:6.6.9.7-5ubuntu3.2
libmagick++4 8:6.6.9.7-5ubuntu3.2

Ubuntu Security Notice USN-1538-1
August 14, 2012

linux-lts-backport-natty vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-lts-backport-natty: Linux kernel backport from Natty

Details:

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2372)

An error was discovered in the Linux kernel's memory subsystem (hugetlb).
An unprivileged local user could exploit this flaw to cause a denial of
service (crash the system). (CVE-2012-2390)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
linux-image-2.6.38-15-generic 2.6.38-15.65~lucid1
linux-image-2.6.38-15-generic-pae 2.6.38-15.65~lucid1
linux-image-2.6.38-15-server 2.6.38-15.65~lucid1
linux-image-2.6.38-15-virtual 2.6.38-15.65~lucid1

After a standard system update you need to reboot your computer to make
all the necessary changes.

Ubuntu Security Notice USN-1539-1
August 14, 2012

linux-lts-backport-oneiric vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-lts-backport-oneiric: Linux kernel backport from Oneiric

Details:

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)

Ulrich Obergfell discovered an error in the Linux kernel's memory
management subsystem on 32 bit PAE systems with more than 4GB of memory
installed. A local unprivileged user could exploit this flaw to crash the
system. (CVE-2012-2373)

A flaw was discovered in the Linux kernel's epoll system call. An
unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which
is used to mount some CD-ROMs and DVDs. An unprivileged local user could
use these flaws to crash the system. (CVE-2012-3400)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
linux-image-3.0.0-24-generic 3.0.0-24.40~lucid1
linux-image-3.0.0-24-generic-pae 3.0.0-24.40~lucid1
linux-image-3.0.0-24-server 3.0.0-24.40~lucid1
linux-image-3.0.0-24-virtual 3.0.0-24.40~lucid1

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.

Ubuntu Security Notice USN-1514-1
August 10, 2012

linux-ti-omap4 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-ti-omap4: Linux kernel for OMAP4

Details:

A flaw was discovered in the Linux kernel's macvtap device driver, which is
used in KVM (Kernel-based Virtual Machine) to create a network bridge
between host and guest. A privleged user in a guest could exploit this flaw
to crash the host, if the vhost_net module is loaded with the
experimental_zcopytx option enabled. (CVE-2012-2119)

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual
Machine) subsystem handled MSI (Message Signaled Interrupts). A local
unprivileged user could exploit this flaw to cause a denial of service or
potentially elevate privileges. (CVE-2012-2137)

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2372)

Ulrich Obergfell discovered an error in the Linux kernel's memory
management subsystem on 32 bit PAE systems with more than 4GB of memory
installed. A local unprivileged user could exploit this flaw to crash the
system. (CVE-2012-2373)

Dan Rosenberg discovered flaws in the Linux kernel's NCI (Near Field
Communication Controller Interface). A remote attacker could exploit these
flaws to crash the system or potentially execute privileged code.
(CVE-2012-3364)

A flaw was discovered in the Linux kernel's epoll system call. An
unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which
is used to mount some CD-ROMs and DVDs. An unprivileged local user could
use these flaws to crash the system. (CVE-2012-3400)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
linux-image-3.2.0-1417-omap4 3.2.0-1417.23

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.

linux vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 12.04 LTS

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux: Linux kernel

Details:

A flaw was discovered in the Linux kernel's macvtap device driver, which is
used in KVM (Kernel-based Virtual Machine) to create a network bridge
between host and guest. A privleged user in a guest could exploit this flaw
to crash the host, if the vhost_net module is loaded with the
experimental_zcopytx option enabled. (CVE-2012-2119)

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual
Machine) subsystem handled MSI (Message Signaled Interrupts). A local
unprivileged user could exploit this flaw to cause a denial of service or
potentially elevate privileges. (CVE-2012-2137)

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2372)

Ulrich Obergfell discovered an error in the Linux kernel's memory
management subsystem on 32 bit PAE systems with more than 4GB of memory
installed. A local unprivileged user could exploit this flaw to crash the
system. (CVE-2012-2373)

Dan Rosenberg discovered flaws in the Linux kernel's NCI (Near Field
Communication Controller Interface). A remote attacker could exploit these
flaws to crash the system or potentially execute privileged code.
(CVE-2012-3364)

A flaw was discovered in the Linux kernel's epoll system call. An
unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which
is used to mount some CD-ROMs and DVDs. An unprivileged local user could
use these flaws to crash the system. (CVE-2012-3400)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 12.04 LTS:
linux-image-3.2.0-29-generic 3.2.0-29.46
linux-image-3.2.0-29-generic-pae 3.2.0-29.46
linux-image-3.2.0-29-highbank 3.2.0-29.46
linux-image-3.2.0-29-omap 3.2.0-29.46

Details:

Andy Adamson discovered a flaw in the Linux kernel's NFSv4 implementation.
A remote NFS server (attacker) could exploit this flaw to cause a denial of
service. (CVE-2011-4131)

Steve Grubb reported a flaw with Linux fscaps (file system base
capabilities) when used to increase the permissions of a process. For
application on which fscaps are in use a local attacker can disable address
space randomization to make attacking the process with raised privileges
easier. (CVE-2012-2123)

An error was discovered in the Linux kernel's network TUN/TAP device
implementation. A local user with access to the TUN/TAP interface (which is
not available to unprivileged users until granted by a root user) could
exploit this flaw to crash the system or potential gain administrative
privileges. (CVE-2012-2136)

Stephan Mueller reported a flaw in the Linux kernel's dl2k network driver's
handling of ioctls. An unprivileged local user could leverage this flaw to
cause a denial of service. (CVE-2012-2313)
