Releases

Packages

  • linux-lts-backport-maverick - Linux kernel backport from Maverick

Details

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)

Update instructions

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

Ubuntu 10.04

After a standard system update you need to reboot your computer to make
all the necessary changes.
