could potentially exploit this to execute arbitrary code with the
privileges of the user invoking Thunderbird. (CVE-2014-1524)

Mariusz Mlynski discovered that sites with notification permissions can
run script in a privileged context in some circumstances. If a user had
enabled scripting, an attacker could exploit this to execute arbitrary
code with the privileges of the user invoking Thunderbird. (CVE-2014-1529)

It was discovered that browser history navigations could be used to load
a site with the addressbar displaying the wrong address. If a user had
enabled scripting, an attacker could potentially exploit this to conduct
cross-site scripting or phishing attacks. (CVE-2014-1530)

A use-after-free was discovered when resizing images in some
circumstances. If a user had enabled scripting, an attacker could
potentially exploit this to cause a denial of service via application
crash or execute arbitrary code with the privileges of the user invoking
Thunderbird. (CVE-2014-1531)

Tyson Smith and Jesse Schwartzentruber discovered a use-after-free during
host resolution in some circumstances. An attacker could potentially
exploit this to cause a denial of service via application crash or execute

Subject: Ubuntu 12.10 (Quantal Quetzal) reaches End of Life on May 16
2014
Message-ID: <20140430235145.GU28005@0c3.net>
Content-Type: text/plain; charset=us-ascii

Ubuntu announced its 12.10 (Quantal Quetzal) release more than 18 months
ago, on October 18, 2012. Since changes to the Ubuntu support cycle
mean that Ubuntu 13.04 has reached end of life before Ubuntu 12.10, the
support cycle for Ubuntu 12.10 has been extended slightly to overlap
with the release of Ubuntu 14.04 LTS. This allowing users to move
directly from Ubuntu 12.10 to Ubuntu 14.04 LTS (via Ubuntu 13.10).

This period of overlap is now coming to a close, and we will be retiring
Ubuntu 12.10 on Friday, May 16, 2014. At that time, Ubuntu Security
Notices will no longer include information or updated packages for
Ubuntu 12.10.

The supported upgrade path from Ubuntu 12.10 is via Ubuntu 13.10, though
we highly recommend that once you've upgraded to 13.10, you continue to
upgrade through to 14.04, as 13.10's support will end in July.

Instructions and caveats for the upgrade may be found at:

https://help.ubuntu.com/community/SaucyUpgrades
https://help.ubuntu.com/community/TrustyUpgrades

Ubuntu 13.10 and 14.04 continue to be actively supported with security
updates and select high-impact bug fixes. Announcements of security
updates for Ubuntu releases are sent to the ubuntu-security-announce
mailing list, information about which may be found at:

https://lists.ubuntu.com/mailman/listinfo/ubuntu-security-announce

Since its launch in October 2004 Ubuntu has become one of the most
highly regarded Linux distributions with millions of users in homes,
schools, businesses and governments around the world. Ubuntu is Open
Source software, costs nothing to download, and users are free to
customize or alter their software in order to meet their needs.

On behalf of the Ubuntu Release Team,

Adam Conrad

Ubuntu Security Notice USN-2173-1
April 26, 2014

linux 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: Linux kernel

Details:

A flaw was discovered in the Linux kernel's handling of SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A
remote attacked could exploit this flaw to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-58-386 2.6.32-58.120
linux-image-2.6.32-58-generic 2.6.32-58.120
linux-image-2.6.32-58-generic-pae 2.6.32-58.120
linux-image-2.6.32-58-ia64 2.6.32-58.120
linux-image-2.6.32-58-lpia 2.6.32-58.120
linux-image-2.6.32-58-powerpc 2.6.32-58.120
linux-image-2.6.32-58-powerpc-smp 2.6.32-58.120
linux-image-2.6.32-58-powerpc64-smp 2.6.32-58.120
linux-image-2.6.32-58-preempt 2.6.32-58.120
linux-image-2.6.32-58-server 2.6.32-58.120
linux-image-2.6.32-58-sparc64 2.6.32-58.120
linux-image-2.6.32-58-sparc64-smp 2.6.32-58.120
linux-image-2.6.32-58-versatile 2.6.32-58.120
linux-image-2.6.32-58-virtual 2.6.32-58.120

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.

==========================================================================

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-ec2: Linux kernel for EC2

Details:

A flaw was discovered in the Linux kernel's handling of SCTP handshake. A
remote attacker could exploit this flaw to cause a denial of service
(system crash). (CVE-2014-0101)

An error was discovered in the Linux kernel's DCCP protocol support. A
remote attacked could exploit this flaw to cause a denial of service
(system crash) or possibly execute arbitrary code. (CVE-2014-2523)

Update instructions:

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

Ubuntu 10.04 LTS:
linux-image-2.6.32-363-ec2 2.6.32-363.76

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-quantal 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-quantal: Linux hardware enablement kernel from Quantal

Details:

A flaw was discovered in the Kernel Virtual Machine (KVM) subsystem of the
Linux kernel. A guest OS user could exploit this flaw to execute arbitrary
code on the host OS. (CVE-2014-0049)

Al Viro discovered an error in how CIFS in the Linux kernel handles
uncached write operations. An unprivileged local user could exploit this
flaw to cause a denial of service (system crash), obtain sensitive
information from kernel memory, or possibly gain privileges.
(CVE-2014-0069)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-49-generic 3.5.0-49.73~precise1

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
