USN-966-1 -- linux, linux-{source-2.6.15,ec2,mvl-dove,ti-omap} vulnerabilities  

Junjiro R. Okajima discovered that knfsd did not correctly handle strict overcommit. A local attacker could exploit this to crash knfsd, leading to a denial of service. Chris Guo, Jukka Taimisto, and Olli Jarva discovered that SCTP did not correctly handle invalid parameters. A remote attacker could send specially crafted traffic that could crash the system, leading to a denial of service. Mario Mikocevic discovered that GFS2 did not correctly handle certain quota structures. A local attacker could exploit this to crash the system, leading to a denial of service. Toshiyuki Okajima discovered that the kernel keyring did not correctly handle dead keyrings. A local attacker could exploit this to crash the system, leading to a denial of service. Brad Spengler discovered that Sparc did not correctly implement non-executable stacks. This made userspace applications vulnerable to exploits that would have been otherwise blocked due to non-executable memory protections. Dan Rosenberg discovered that the btrfs clone function did not correctly validate permissions. A local attacker could exploit this to read sensitive information, leading to a loss of privacy. Dan Rosenberg discovered that GFS2 set_flags function did not correctly validate permissions. A local attacker could exploit this to gain access to files, leading to a loss of privacy and potential privilege escalation. Shi Weihua discovered that btrfs xattr_set_acl function did not correctly validate permissions. A local attacker could exploit this to gain access to files, leading to a loss of privacy and potential privilege escalation. Andre Osterhues discovered that eCryptfs did not correctly calculate hash values. A local attacker with certain uids could exploit this to crash the system or potentially gain root privileges
