Ubuntu Security Notice 4946-1 - It was discovered that the DRM subsystem in the Linux kernel contained double-free vulnerabilities. A privileged attacker could possibly use this to cause a denial of service or possibly execute arbitrary code. Olivier Benjamin, Norbert Manthey, Martin Mazein, and Jan H. Schoenherr discovered that the Xen paravirtualization backend in the Linux kernel did not properly propagate errors to frontend drivers in some situations. An attacker in a guest VM could possibly use this to cause a denial of service. Various other issues were also addressed.
