Ubuntu Security Notice USN-2257-1
June 26, 2014

samba vulnerabilities
==========================================================================

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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Samba.

Software Description:
- samba: SMB/CIFS file, print, and login server for Unix

Details:

Christof Schmitt discovered that Samba incorrectly initialized a certain
response field when vfs shadow copy was enabled. A remote authenticated
attacker could use this issue to possibly obtain sensitive information.
This issue only affected Ubuntu 13.10 and Ubuntu 14.04 LTS. (CVE-2014-0178)

It was discovered that the Samba internal DNS server incorrectly handled QR
fields when processing incoming DNS messages. A remote attacker could use
this issue to cause Samba to consume resources, resulting in a denial of
service. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-0239)

Daniel Berteaud discovered that the Samba NetBIOS name service daemon
incorrectly handled certain malformed packets. A remote attacker could use
this issue to cause Samba to consume resources, resulting in a denial of
service. This issue only affected Ubuntu 12.04 LTS, Ubuntu 13.10, and
Ubuntu 14.04 LTS. (CVE-2014-0244)

Simon Arlott discovered that Samba incorrectly handled certain unicode path
names. A remote authenticated attacker could use this issue to cause Samba
to stop responding, resulting in a denial of service. (CVE-2014-3493)

Update instructions:

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

Ubuntu 14.04 LTS:
samba 2:4.1.6+dfsg-1ubuntu2.14.04.2

Ubuntu 13.10:
samba 2:3.6.18-1ubuntu3.3

Ubuntu 12.04 LTS:
samba 2:3.6.3-2ubuntu2.11

Ubuntu 10.04 LTS:
samba 2:3.4.7~dfsg-1ubuntu3.15

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

gnupg, gnupg2 vulnerability
==========================================================================

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

- Ubuntu 14.04 LTS
- Ubuntu 13.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

GnuPG could be made to hang if it processed a specially crafted message.

Software Description:
- gnupg: GNU privacy guard - a free PGP replacement
- gnupg2: GNU privacy guard - a free PGP replacement

Details:

Jean-Ren? Reinhard, Olivier Levillain and Florian Maury discovered that
GnuPG incorrectly handled certain OpenPGP messages. If a user or automated
system were tricked into processing a specially-crafted message, GnuPG
could consume resources, resulting in a denial of service.

Update instructions:

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

Ubuntu 14.04 LTS:
gnupg 1.4.16-1ubuntu2.1
gnupg2 2.0.22-3ubuntu1.1

Ubuntu 13.10:
gnupg 1.4.14-1ubuntu2.2

Ubuntu Security Notice USN-2259-1
June 27, 2014

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:

Salva Peir? discovered an information leak in the Linux kernel's media-
device driver. A local attacker could exploit this flaw to obtain sensitive
information from kernel memory. (CVE-2014-1739)

A bounds check error was discovered in the socket filter subsystem of the
Linux kernel. A local user could exploit this flaw to cause a denial of
service (system crash) via crafted BPF instructions. (CVE-2014-3144)

A remainder calculation error was discovered in the socket filter subsystem
of the Linux kernel. A local user could exploit this flaw to cause a denial
of service (system crash) via crafted BPF instructions. (CVE-2014-3145)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-65-generic 3.2.0-65.98
linux-image-3.2.0-65-generic-pae 3.2.0-65.98
linux-image-3.2.0-65-highbank 3.2.0-65.98
linux-image-3.2.0-65-omap 3.2.0-65.98
linux-image-3.2.0-65-powerpc-smp 3.2.0-65.98
linux-image-3.2.0-65-powerpc64-smp 3.2.0-65.98
linux-image-3.2.0-65-virtual 3.2.0-65.98

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-lts-trusty 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-lts-trusty: Block storage devices (udeb)

Details:

A flaw was discovered in the Linux kernel's pseudo tty (pty) device. An
unprivileged user could exploit this flaw to cause a denial of service
(system crash) or potentially gain administrator privileges.
(CVE-2014-0196)

Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An
unprivileged local user could exploit this flaw to cause a denial of
service (system crash) or gain administrative privileges. (CVE-2014-3153)

Matthew Daley reported an information leak in the floppy disk driver of the
Linux kernel. An unprivileged local user could exploit this flaw to obtain
potentially sensitive information from kernel memory. (CVE-2014-1738)

Matthew Daley reported a flaw in the handling of ioctl commands by the
floppy disk driver in the Linux kernel. An unprivileged local user could
exploit this flaw to gain administrative privileges if the floppy disk
module is loaded. (CVE-2014-1737)

A flaw was discovered in the handling of network packets when mergeable
buffers are disabled for virtual machines in the Linux kernel. Guest OS
users may exploit this flaw to cause a denial of service (host OS crash) or
possibly gain privilege on the host OS. (CVE-2014-0077)

An information leak was discovered in the netfilter subsystem of the Linux
kernel. An attacker could exploit this flaw to obtain sensitive information
from kernel memory. (CVE-2014-2568)

A flaw was discovered in the Linux kernel's ping sockets. An unprivileged
local user could exploit this flaw to cause a denial of service (system
crash) or possibly gain privileges via a crafted application.
(CVE-2014-2851)

Sasha Levin reported a bug in the Linux kernel's virtual memory management
subsystem. An unprivileged local user could exploit this flaw to cause a
denial of service (system crash). (CVE-2014-3122)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.13.0-30-generic 3.13.0-30.54~precise2
linux-image-3.13.0-30-generic-lpae 3.13.0-30.54~precise2

Controlling Access to Data Is as Important as Managing Devices

by Orin Thomas

Many people underestimate the value of data until they lose it. Only when data is lost, or stolen, do most people realize that it's the data itself, not the equipment used to store it, that's the valuable thing.

New Security Update Disables RC4 in Transport Layer Security

by Rod Trent

Reported first in May 2014, an update is now available for practically all versions of supported Windows versions that are running the Microsoft .NET Framework 3.5 through 4.5.x. The update disables RC4 (stream cipher for encryption and decryption) communications in the Transport Layer Security (TLS – the latest version of Secure Sockets Layer protocol) due to a vulnerability that could allow an attacker to perform man-in-the-middle attacks and recover plaintext from encrypted sessions.
