[USN-1970-1] Linux kernel (Quantal HWE) vulnerabilities

Severity Medium

CVEs 3

Several security issues were fixed in the kernel.

Vince Weaver discovered a flaw in the perf subsystem of the Linux kernel on
ARM platforms. A local user could exploit this flaw to gain privileges or
cause a denial of service (system crash). (CVE-2013-4254)

A failure to validate block numbers was discovered in the Linux kernel's
implementation of the XFS filesystem. A local user can cause a denial of
service (system crash) if they can mount, or cause to be mounted a
corrupted or special crafted XFS filesystem. (CVE-2013-1819)

An information leak was discovered in the Linux kernel when reading
broadcast messages from the notify_policy interface of the IPSec
key_socket. A local user could exploit this flaw to examine potentially
sensitive information in kernel memory. (CVE-2013-2237)
