Ubuntu Security Notice 1204-1 - Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that multiple terminal ioctls did not correctly initialize structure memory. A local attacker could exploit this to read portions of kernel stack memory, leading to a loss of privacy. Various other issues were also addressed.

Ubuntu Security Notice 1202-1 - Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. A local user could exploit this to read kernel stack memory, leading to a loss of privacy. Brad Spengler discovered that stack memory for new a process was not correctly calculated. A local attacker could exploit this to crash the system, leading to a denial of service. Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Various other issues were also addressed.

Ubuntu Security Notice 1167-1 - Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. 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.

Ubuntu Security Notice 1093-1 - Joel Becker discovered that OCFS2 did not correctly validate on-disk symlink structures. Ben Hutchings discovered that the ethtool interface did not correctly check certain sizes. Eric Dumazet discovered that many network functions could leak kernel stack contents. Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. A large number of additional vulnerabilities have also been address.

Ubuntu Security Notice 1071-1 - Tavis Ormandy discovered that the Linux kernel did not properly implement exception fixup. A local attacker could exploit this to crash the kernel, leading to a denial of service. Dan Rosenberg discovered that the Linux kernel TIPC implementation contained multiple integer signedness errors. A local attacker could exploit this to gain root privileges. Dan Rosenberg discovered that the Linux kernel X.25 implementation incorrectly parsed facilities. A remote attacker could exploit this to crash the kernel, leading to a denial of service. 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. 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. 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. Various other issues were also addressed.

Mandriva Linux Security Advisory 2011-029 - Multiple vulnerabilities have been discovered and fixed in the Linux 2.6 kernel. The X.25 implementation does not properly parse facilities, which allows remote attackers to cause a denial of service (heap memory corruption and panic) or possibly have unspecified other impact via malformed data, a different vulnerability than CVE-2010-4164. The bcm_connect function Broadcast Manager in the Controller Area Network implementation in the Linux creates a publicly accessible file with a filename containing a kernel memory address, which allows local users to obtain potentially sensitive information about kernel memory use by listing this filename. The install_special_mapping function in mm/mmap.c does not make an expected security_file_mmap function call, which allows local users to bypass intended mmap_min_addr restrictions and possibly conduct NULL pointer dereference attacks via a crafted assembly-language application. Various other issues have also been addressed.

Debian Linux Security Advisory 2126-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leak.
