Details

A flaw was discovered in the Linux kernel's dm snapshot facility. A remote
authenticated user could exploit this flaw to obtain sensitive information
or modify/corrupt data. (CVE-2013-4299)

Alan Chester reported a flaw in the IPv6 Stream Control Transmission
Protocol (SCTP) of the Linux kernel. A remote attacker could exploit this
flaw to obtain sensitive information by sniffing network traffic.
(CVE-2013-4350)

Dmitry Vyukov reported a flaw in the Linux kernel's handling of IPv6 UDP
Fragmentation Offload (UFO) processing. A remote attacker could leverage
this flaw to cause a denial of service (system crash). (CVE-2013-4387)

A flaw was discovered in the Linux kernel's fib6 error-code encoding for
IPv6. A local user with the CAT_NET_ADMIN capability could exploit this
flaw to cause a denial of service (system crash). (CVE-2013-6431)

Update instructions

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

Ubuntu 12.04

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.
