"Andy Adamson discovered a flaw in the Linux kernel's NFSv4
implementation. A remote NFS server (attacker) could exploit this flaw
to cause a denial of service. (CVE-2011-4131)

A flaw was discovered in the Linux kernel's KVM (kernel virtual
machine). An administrative user in the guest OS could leverage this
flaw to cause a denial of service in the host OS. (CVE-2012-2121)

Schacher Raindel discovered a flaw in the Linux kernel's memory
handling when hugetlb is enabled. An unprivileged local attacker could
exploit this flaw to cause a denial of service and potentially gain
higher privileges. (CVE-2012-2133)

Stephan Mueller reported a flaw in the Linux kernel's dl2k network
driver's handling of ioctls. An unprivileged local user could leverage
this flaw to cause a denial of service. (CVE-2012-2313)

Timo Warns reported multiple flaws in the Linux kernel's hfsplus
filesystem. An unprivileged local user could exploit these flaws to
gain root system priviliges. (CVE-2012-2319)

Xi Wang discovered a flaw in the Linux kernel's i915 graphics driver
handling of cliprect on 32 bit systems. An unprivileged local attacker
could leverage this flaw to cause a denial of service or potentially
gain root privileges. (CVE-2012-2383)

Xi Wang discovered a flaw in the Linux kernel's i915 graphics driver
handling of buffer_count on 32 bit systems. An unprivileged local
attacker could leverage this flaw to cause a denial of service or
potentially gain root privileges. (CVE-2012-2384).

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."
