Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 1299-1 - Peter Huewe discovered an information leak in the handling of reading security-related TPM data. A local, unprivileged user could read the results of a previous TPM command. A bug was discovered in the XFS filesystem's handling of pathnames. A local attacker could exploit this to crash the system, leading to a denial of service, or gain root privileges. Nick Bowler discovered the kernel GHASH message digest algorithm incorrectly handled error conditions. A local attacker could exploit this to cause a kernel oops. Various other issues were also addressed.
