Ubuntu Security Notice USN-1677-1
December 20, 2012

linux vulnerability
==========================================================================

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

- Ubuntu 11.10

Summary:

The system could be made to crash under certain conditions.

Software Description:
- linux: Linux kernel

Details:

A flaw was discovered in the Linux kernel's handling of new hot-plugged
memory. An unprivileged local user could exploit this flaw to cause a
denial of service by crashing the system.

Update instructions:

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

Ubuntu 11.10:
linux-image-3.0.0-29-generic 3.0.0-29.46
linux-image-3.0.0-29-generic-pae 3.0.0-29.46
linux-image-3.0.0-29-omap 3.0.0-29.46
linux-image-3.0.0-29-powerpc 3.0.0-29.46
linux-image-3.0.0-29-powerpc-smp 3.0.0-29.46
linux-image-3.0.0-29-powerpc64-smp 3.0.0-29.46
linux-image-3.0.0-29-server 3.0.0-29.46
linux-image-3.0.0-29-virtual 3.0.0-29.46

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.

Summary:

USN-1589-1 exposed a regression in the GNU C Library floating point parser.

Software Description:
- glibc: GNU C Library

Details:

USN-1589-1 fixed vulnerabilities in the GNU C Library. One of the updates
exposed a regression in the floating point parser. This update fixes the
problem.

We apologize for the inconvenience.

Original advisory details:

It was discovered that positional arguments to the printf() family
of functions were not handled properly in the GNU C Library. An
attacker could possibly use this to cause a stack-based buffer
overflow, creating a denial of service or possibly execute arbitrary
code. (CVE-2012-3404, CVE-2012-3405, CVE-2012-3406)
It was discovered that multiple integer overflows existed in the
strtod(), strtof() and strtold() functions in the GNU C Library. An
attacker could possibly use this to trigger a stack-based buffer
overflow, creating a denial of service or possibly execute arbitrary
code. (CVE-2012-3480)

Update instructions:

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

Ubuntu 8.04 LTS:
libc6 2.7-10ubuntu8.3

Ubuntu Security Notice USN-1668-1
December 17, 2012

apport update
==========================================================================

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

- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

A hardening measure was added to apport.

Software Description:
- apport: automatically generate crash reports for debugging

Details:

Dan Rosenberg discovered that an application running under an AppArmor
profile that allowed unconfined execution of apport-bug could escape
confinement by calling apport-bug with a crafted environment. While not a
vulnerability in apport itself, this update mitigates the issue by
sanitizing certain variables in the apport-bug shell script.

Update instructions:

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

Ubuntu 12.04 LTS:
apport 2.0.1-0ubuntu15.1

Ubuntu 11.10:
apport 1.23-0ubuntu4.1

Ubuntu 10.04 LTS:
apport 1.13.3-0ubuntu2.2

In general, a standard system update will make all the necessary changes.

firefox regressions
==========================================================================

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

- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 11.10
- Ubuntu 10.04 LTS

Summary:

Regressions were introduced in the last Firefox update.

Software Description:
- firefox: Mozilla Open Source web browser

Details:

USN-1638-1 fixed vulnerabilities in Firefox. The new packages introduced
regressions in cookies handling and the User Agent string. This update fixes
the problem.

Original advisory details:

Gary Kwong, Jesse Ruderman, Christian Holler, Bob Clary, Kyle Huey, Ed
Morley, Chris Lord, Boris Zbarsky, Julian Seward, Bill McCloskey, and
Andrew McCreight discovered multiple memory safety issues affecting
Firefox. If the user were tricked into opening a specially crafted page, an
attacker could possibly exploit these to cause a denial of service via
application crash, or potentially execute code with the privileges of the
user invoking Firefox. (CVE-2012-5842, CVE-2012-5843)

Atte Kettunen discovered a buffer overflow while rendering GIF format
images. An attacker could exploit this to possibly execute arbitrary code
as the user invoking Firefox. (CVE-2012-4202)

It was discovered that the evalInSandbox function's JavaScript sandbox
context could be circumvented. An attacker could exploit this to perform a
cross-site scripting (XSS) attack or steal a copy of a local file if the
user has installed an add-on vulnerable to this attack. With cross-site
scripting vulnerabilities, if a user were tricked into viewing a specially
crafted page, a remote attacker could exploit this to modify the contents,
or steal confidential data, within the same domain. (CVE-2012-4201)

Jonathan Stephens discovered that combining vectors involving the setting
of Cascading Style Sheets (CSS) properties in conjunction with SVG text
could cause Firefox to crash. If a user were tricked into opening a
malicious web page, an attacker could cause a denial of service via
application crash or execute arbitrary code with the privliges of the user
invoking the program. (CVE-2012-5836)

It was discovered that if a javascript: URL is selected from the list of
Firefox "new tab" page, the script will inherit the privileges of the
privileged "new tab" page. This allows for the execution of locally
installed programs if a user can be convinced to save a bookmark of a
malicious javascript: URL. (CVE-2012-4203)

Scott Bell discovered a memory corruption issue in the JavaScript engine.
If a user were tricked into opening a malicious website, an attacker could
exploit this to execute arbitrary JavaScript code within the context of
another website or arbitrary code as the user invoking the program.
(CVE-2012-4204)

Gabor Krizsanits discovered that XMLHttpRequest objects created within
sandboxes have the system principal instead of the sandbox principal. This
can lead to cross-site request forgery (CSRF) or information theft via an
add-on running untrusted code in a sandbox. (CVE-2012-4205)

Peter Van der Beken discovered XrayWrapper implementation in Firefox does
not consider the compartment during property filtering. An attacker could
use this to bypass intended chrome-only restrictions on reading DOM object
properties via a crafted web site. (CVE-2012-4208)

Bobby Holley discovered that cross-origin wrappers were allowing write
actions on objects when only read actions should have been properly
allowed. This can lead to cross-site scripting (XSS) attacks. With
cross-site scripting vulnerabilities, if a user were tricked into viewing a
specially crafted page, a remote attacker could exploit this to modify the
contents, or steal confidential data, within the same domain.
(CVE-2012-5841)

Masato Kinugawa discovered that when HZ-GB-2312 charset encoding is used
for text, the "~" character will destroy another character near the chunk
delimiter. This can lead to a cross-site scripting (XSS) attack in pages
encoded in HZ-GB-2312. With cross-site scripting vulnerabilities, if a user
were tricked into viewing a specially crafted page, a remote attacker could
exploit this to modify the contents, or steal confidential data, within
the same domain. (CVE-2012-4207)

Masato Kinugawa discovered that scripts entered into the Developer Toolbar
could run in a chrome privileged context. An attacker could use this
vulnerability to conduct cross-site scripting (XSS) attacks or execute
arbitrary code as the user invoking Firefox. With cross-site scripting
vulnerabilities, if a user were tricked into viewing a specially crafted
page, a remote attacker could exploit this to modify the contents, or
steal confidential data, within the same domain. (CVE-2012-5837)

Mariusz Mlynski discovered that the location property can be accessed by
binary plugins through top.location with a frame whose name attribute's
value is set to "top". This can allow for possible cross-site scripting
(XSS) attacks through plugins. With cross-site scripting vulnerabilities,
if a user were tricked into viewing a specially crafted page, a remote
attacker could exploit this to modify the contents, or steal confidential
data, within the same domain. (CVE-2012-4209)

Mariusz Mlynski discovered that when a maliciously crafted stylesheet is
inspected in the Style Inspector, HTML and CSS can run in a chrome
privileged context without being properly sanitized first. If a user were
tricked into opening a malicious web page, an attacker could execute
arbitrary code with the privliges of the user invoking the program.
(CVE-2012-4210)

Abhishek Arya discovered multiple use-after-free and buffer overflow issues
in Firefox. If a user were tricked into opening a malicious page, an
attacker could exploit these to execute arbitrary code as the user invoking
the program. (CVE-2012-4214, CVE-2012-4215, CVE-2012-4216, CVE-2012-5829,
CVE-2012-5839, CVE-2012-5840, CVE-2012-4212, CVE-2012-4213, CVE-2012-4217,
CVE-2012-4218)

Several memory corruption flaws were discovered in Firefox. If a user were
tricked into opening a malicious page, an attacker could exploit these to
execute arbitrary code as the user invoking the program. (CVE-2012-5830,
CVE-2012-5833, CVE-2012-5835, CVE-2012-5838)

Update instructions:

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

Ubuntu 12.10:
firefox 17.0.1+build1-0ubuntu0.12.10.1

Ubuntu 12.04 LTS:
firefox 17.0.1+build1-0ubuntu0.12.04.1

Ubuntu 11.10:
firefox 17.0.1+build1-0ubuntu0.11.10.1

Ubuntu 10.04 LTS:
