Ubuntu Security Notice USN-3910-1
Ubuntu Security Notice 3910-1 – It was discovered that the f2fs filesystem implementation in the Linux kernel did not handle the noflush_merge mount option correctly. An attacker could use this to cause a denial of service. It was discovered that the procfs filesystem did not properly handle processes mapping some memory elements onto files. A local attacker could use this to block utilities that examine the procfs filesystem to report operating system state, such as ps. Various other issues were also addressed.
