VMware Security Advisory 2011-0012 - VMware ESXi and ESX updates to third party libraries and ESX Service Console address several security issues.
09895b515d192ac17d0b7edd6177d76bUbuntu Security Notice 1119-1 - Multiple security flaws have been fixed in the OMAP4 port of the Linux kernel.
c166b2a4edaba2cfee36fd0164fbf8a9Mandriva Linux Security Advisory 2011-051 - The Linux 2.6 kernel has been updated to mitigate multiple vulnerabilities related to denial of service, arbitrary code execution, stack memory disclosure, restriction bypass, and more.
f2ce03c37e6b21cbf22fe118915e6000Ubuntu Security Notice 1072-1 - Multiple vulnerabilities have been discovered and addressed in the Linux kernel. Gleb Napatov discovered that KVM did not correctly check certain privileged operations. Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. Dan Rosenberg discovered that several network ioctls did not clear kernel memory correctly. Dan Jacobson discovered that ThinkPad video output was not correctly access controlled. Various other issues have also been addressed.
27c3f06a2a4304897f036ea3734a09eaMandriva 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.
b09673d46bd0c26aeac9afa523e5a306Ubuntu Security Notice 1057-1 - Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. A remote attacker could exploit this to read or write disk blocks that had changed file assignment or had become unlinked, leading to a loss of privacy. 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. Kees Cook and Vasiliy Kulikov discovered that the shm interface did not clear kernel memory correctly. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy.
5ebc82f8363d3d96ef4dc449e56f3464Ubuntu Security Notice 1041-1 - Dan Rosenberg discovered that the btrfs filesystem did not correctly validate permissions when using the clone function. Dave Chinner discovered that the XFS filesystem did not correctly order inode lookups when exported by NFS. Kees Cook discovered that the Intel i915 graphics driver did not correctly validate memory regions. Various other issues have also been addressed.
d939ab86ad3f2ab7e69a390de4446f67Debian 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.
