Ubuntu Security Notice 5045-1 - Norbert Slusarek discovered that the CAN broadcast manger protocol implementation in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to expose sensitive information. It was discovered that the bluetooth subsystem in the Linux kernel did not properly handle HCI device initialization failure, leading to a double-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Various other issues were also addressed.
