Ubuntu Security Notice 1212-1 - Goldwyn Rodrigues discovered that the OCFS2 filesystem did not correctly clear memory when writing certain file holes. A local attacker could exploit this to read uninitialized data from the disk, leading to a loss of privacy. Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. Various other issues were also addressed.
bb1d77163194f3843168c4d7dba75680Ubuntu Security Notice 1168-1 - Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. Neil Horman discovered that NFSv4 did not correctly handle certain orders of operation with ACL data. A remote attacker with access to an NFSv4 mount could exploit this to crash the system, leading to a denial of service. Various other issues were also addressed.
008971a8f4ff5922d49f6b7f64cd0166Ubuntu Security Notice 1161-1 - Vasiliy Kulikov discovered that kvm did not correctly clear memory. A local attacker could exploit this to read portions of the kernel stack, leading to a loss of privacy. Timo Warns discovered that the LDM disk partition handling code did not correctly handle certain values. By inserting a specially crafted disk device, a local attacker could exploit this to gain root privileges. Various other issues were also addressed.
4ea4888b93fd18674ef57689a4618ed3Ubuntu Security Notice 1159-1 - 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 addressed.
3d57f1386d9eb0b24e5622f779dd40f7Ubuntu Security Notice 1164-1 - 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. 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.
e70bdd0acf312c2b66cea08dc84f7849Ubuntu Security Notice 1162-1 - 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.

80b92d9d06991549ea0d7aaf09ed86e4Ubuntu 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.
0b27c7685536805308dcb14221dc34a5Debian Linux Security Advisory 2264-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak.
e4fc6508acdcc4816d4b46bbbcd75992Ubuntu Security Notice 1146-1 - Kees Cook discovered that some ethtool functions did not correctly clear heap memory. 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.
71e6b39eab78b5479506bbaad126083fUbuntu Security Notice 1111-1 - Multiple vulnerabilities have been addressed in the Linux 2.6 kernel. 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.
