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)

Dan Rosenberg reported an error in the old ABI compatibility layer of ARM
kernels. A local attacker could exploit this flaw to cause a denial of
service or gain root privileges. (CVE-2011-1759)

Ben Hutchings reported a flaw in the kernel's handling of corrupt LDM
partitions. A local user could exploit this to cause a denial of service or
escalate privileges. (CVE-2011-2182)

The linux kernel did not properly account for PTE pages when deciding which
task to kill in out of memory conditions. A local, unprivileged could
exploit this flaw to cause a denial of service. (CVE-2011-2498)

A flaw was discovered in the TOMOYO LSM's handling of mount system calls.
An unprivileged user could oops the system causing a denial of service.
(CVE-2011-2518)

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)

Update instructions

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