"Aristide Fattori and Roberto Paleari reported a flaw in the Linux
kernel's handling of IPv4 icmp packets. A remote user could exploit
this to cause a denial of service. (CVE-2011-1927)

A flaw was found in the Linux Ethernet bridge's handling of IGMP
(Internet Group Management Protocol) packets. An unprivileged local
user could exploit this flaw to crash the system. (CVE-2011-0716)

Han-Wen Nienhuys reported a flaw in the FUSE kernel module. A local
user who can mount a FUSE file system could cause a denial of service.
(CVE-2011-3353)

A flaw was discovered in the Linux kernel's AppArmor security
interface when invalid information was written to it. An unprivileged
local user could use this to cause a denial of service on the system.
(CVE-2011-3619)

A flaw was found in KVM's Programmable Interval Timer (PIT). When a
virtual interrupt control is not available a local user could use this
to cause a denial of service by starting a timer. (CVE-2011-4622)

A flaw was discovered in the XFS filesystem. If a local user mounts a
specially crafted XFS image it could potential execute arbitrary code
on the system. (CVE-2012-0038)

Chen Haogang discovered an integer overflow that could result in
memory corruption. A local unprivileged user could use this to crash
the system. (CVE-2012-0044).

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."
