Ubuntu Update for Linux kernel vulnerabilities USN-1080-2

Please Install the Updated Packages.

USN-1080-1 fixed vulnerabilities in the Linux kernel. This update provides the corresponding updates for the Linux kernel for use with EC2. Original advisory details: 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. (CVE-2010-3865) 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. (CVE-2010-3875) Vasiliy Kulikov discovered that the Linux kernel sockets implementation did not properly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3876) Vasiliy Kulikov discovered that the TIPC interface did not correctly initialize certain structures. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. (CVE-2010-3877) Nelson Elhage discovered that the Linux kernel IPv4 implementation did not properly audit certain bytecodes in netlink messages. A local attacker could exploit this to cause the kernel to hang, leading to a denial of service. (CVE-2010-3880) It was discovered that multithreaded exec did not handle CPU timers correctly. A local attacker could exploit this to crash the system, leading to a denial of service. (CVE-2010-4248) Krishna Gudipati discovered that the bfa adapter driver did not correctly initialize certain structures. A local attacker could read files in /sys to crash the system, leading to a denial of service. (CVE-2010-4343) Tavis Ormandy discovered that the install_special_mapping function could bypass the mmap_min_addr restriction. A local attacker could exploit this to mmap 4096 bytes below the mmap_min_addr area, possibly improving the chances of performing NULL pointer dereference attacks. (CVE-2010-4346) It was discovered that the ICMP stack did not correctly handle certain unreachable messages. If a remote attacker were able to acquire a socket lock, they could send specially crafted traffic that would crash the system, leading to a denial of service. (CVE-2010-4526) Dan Rosenberg discovered that the OSS subsystem did not handle name termination correctly. A local attacker could exploit this crash the system or gain root privileges. (CVE-2010-4527) Dan Carpenter discovered that the Infiniband driver did not correctly handle certain requests. A local user could exploit this to crash the system or potentially gain root privileges. (CVE-2010-4649, CVE-2011-1044)
