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.

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.
934e3131ff453ae37627f4f3e4e27245ba82027abdbac477246bd7efd898fe63Ubuntu Security Notice 1141-1 - Brad Spengler discovered that the kernel did not correctly account for userspace memory allocations during exec() calls. 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.

Dan Rosenberg discovered multiple flaws in the X.25 facilities parsing. Vegard Nossum discovered that memory garbage collection was not handled correctly for active sockets. Nelson Elhage discovered that the kernel did not correctly handle process cleanup after triggering a recoverable kernel bug. Nelson Elhage discovered that Econet did not correctly handle AUN packets over UDP. Dan Rosenberg discovered that the OSS subsystem did not handle name termination correctly. Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. Dan Carpenter discovered that the TTPCI DVB driver did not check certain values during an ioctl. Jens Kuehnel discovered that the InfiniBand driver contained a race condition. Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values.
