Ubuntu Security Notice 1187-1 - It was discovered that KVM did not correctly initialize certain CPU registers. A local attacker could exploit this to crash the system, leading to a denial of service. Thomas Pollet discovered that the RDS network protocol did not check certain iovec buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Vasiliy Kulikov discovered that the Linux kernel X.25 implementation did not correctly clear kernel memory. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.

A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Dan Rosenberg discovered that the CAN protocol on 64bit systems did not correctly calculate the size of certain buffers. A local attacker could exploit this to crash the system or possibly execute arbitrary code as the root user. Various other issues were also addressed.
4e4395012a3efacb0412aff2ad1192af5495aeffbe292f807d0de267e1af68f2Ubuntu Security Notice 1160-1 - Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy. Dan Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.

A local attacker with CAP_NET_ADMIN privileges could exploit this to read portions of kernel heap memory, leading to a loss of privacy. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.

A local attacker could exploit this to consume all system memory, leading to a denial of service. Alexander Duyck discovered that the Intel Gigabit Ethernet driver did not correctly handle certain configurations. If such a device was configured without VLANs, a remote attacker could crash the system, leading to a denial of service. Various other issues were also discovered.
