"Mathias Krause discovered an information leak in the Linux kernel's
ISO 9660 CDROM file system driver. A local user could exploit this
flaw to examine some of the kernel's heap memory. (CVE-2012-6549)

Mathias Krause discovered a flaw in xfrm_user in the Linux kernel. A
local attacker with NET_ADMIN capability could potentially exploit
this flaw to escalate privileges. (CVE-2013-1826)

A buffer overflow was discovered in the Linux Kernel's USB subsystem
for devices reporting the cdc-wdm class. A specially crafted USB
device when plugged-in could cause a denial of service (system crash)
or possibly execute arbitrary code. (CVE-2013-1860)

An information leak was discovered in the Linux kernel's /dev/dvb
device. A local user could exploit this flaw to obtain sensitive
information from the kernel's stack memory. (CVE-2013-1928)

An information leak in the Linux kernel's dcb netlink interface was
discovered. A local user could obtain sensitive information by
examining kernel stack memory. (CVE-2013-2634).

Note that Tenable Network Security has extracted the preceding
description block directly from the Ubuntu security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
