USN-1968-1: Linux kernel vulnerabilities
First published: Fri Sep 27 2013(Updated: )
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)
