Ubuntu Security Notice USN-1388-1
» ‎ Packet Storm Security Advisories

Ubuntu Security Notice 1388-1 - Paolo Bonzini discovered a flaw in Linux's handling of the SG_IO ioctl command. A local user, or user in a VM could exploit this flaw to bypass restrictions and gain read/write access to all data on the affected block device. A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. Various other issues were also addressed.

Ubuntu Security Notice USN-1363-1
» ‎ Packet Storm Security Advisories

Ubuntu Security Notice 1363-1 - A flaw was found in KVM's Programmable Interval Timer (PIT). When a virtual interrupt control is not available a local user could use this to cause a denial of service by starting a timer. A flaw was discovered in the XFS filesystem. If a local user mounts a specially crafted XFS image it could potential execute arbitrary code on the system. Andy Whitcroft discovered a that the Overlayfs filesystem was not doing the extended permission checks needed by cgroups and Linux Security Modules (LSMs). A local user could exploit this to by-pass security policy and access files that should not be accessible. Various other issues were also addressed.
