Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 4135-1 - Peter Pi discovered a buffer overflow in the virtio network backend implementation in the Linux kernel. An attacker in a guest may be able to use this to cause a denial of service or possibly execute arbitrary code in the host OS. It was discovered that the Linux kernel on PowerPC architectures did not properly handle Facility Unavailable exceptions in some situations. A local attacker could use this to expose sensitive information. Various other issues were also addressed.

Authored by Benjamin M. Romer

It was discovered that a use-after-free error existed in the block layer subsystem of the Linux kernel when certain failure conditions occurred. A local attacker could possibly use this to cause a denial of service (system crash) or possibly execute arbitrary code. It was discovered that the Bluetooth UART implementation in the Linux kernel did not properly check for missing tty operations. A local attacker could use this to cause a denial of service. Various other issues were also addressed.
