Ubuntu Security Notice USN-1833-1
May 24, 2013

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:

Andy Lutomirski discover an error in the Linux kernel's credential handling
on unix sockets. A local user could exploit this flaw to gain
administrative privileges. (CVE-2013-1979)

A buffer overflow vulnerability was discovered in the Broadcom tg3 ethernet
driver for the Linux kernel. A local user could exploit this flaw to cause
a denial of service (crash the system) or potentially escalate privileges
on the system. (CVE-2013-1929)

A flaw was discovered in the Linux kernel's ftrace subsystem interface. A
local user could exploit this flaw to cause a denial of service (system
crash). (CVE-2013-3301)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.2.0-44-generic 3.2.0-44.69
linux-image-3.2.0-44-generic-pae 3.2.0-44.69
linux-image-3.2.0-44-highbank 3.2.0-44.69
linux-image-3.2.0-44-omap 3.2.0-44.69
linux-image-3.2.0-44-powerpc-smp 3.2.0-44.69
linux-image-3.2.0-44-powerpc64-smp 3.2.0-44.69
linux-image-3.2.0-44-virtual 3.2.0-44.69

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 buffer overflow vulnerability was discovered in the Broadcom tg3 ethernet
driver for the Linux kernel. A local user could exploit this flaw to cause
a denial of service (crash the system) or potentially escalate privileges
on the system. (CVE-2013-1929)

A flaw was discovered in the Linux kernel's ftrace subsystem interface. A
local user could exploit this flaw to cause a denial of service (system
crash). (CVE-2013-3301)

Update instructions:

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

Ubuntu 12.04 LTS:
linux-image-3.5.0-31-generic 3.5.0-31.52~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
