Ubuntu Security Notice USN-1844-1
May 30, 2013

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

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

- Ubuntu 12.04 LTS

Summary:

The system could be made to crash or run programs as an administrator if
it received specially crafted network traffic.

Software Description:
- linux: Linux kernel

Details:

Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote
unauthenticated attacker could exploit this flaw to cause a denial of
service (system crash) or potentially gain administrative privileges.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-45-generic 3.2.0-45.70
linux-image-3.2.0-45-generic-pae 3.2.0-45.70
linux-image-3.2.0-45-highbank 3.2.0-45.70
linux-image-3.2.0-45-omap 3.2.0-45.70
linux-image-3.2.0-45-powerpc-smp 3.2.0-45.70
linux-image-3.2.0-45-powerpc64-smp 3.2.0-45.70
linux-image-3.2.0-45-virtual 3.2.0-45.70

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 vulnerability
==========================================================================

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

- Ubuntu 12.04 LTS

Summary:

The system could be made to crash or run programs as an administrator if
it received specially crafted network traffic.

Software Description:
- linux-lts-quantal: Linux hardware enablement kernel from Quantal

Details:

Kees Cook discovered a flaw in the Linux kernel's iSCSI subsystem. A remote
unauthenticated attacker could exploit this flaw to cause a denial of
service (system crash) or potentially gain administrative privileges.

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-32-generic 3.5.0-32.53~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
