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 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.

bd92ad19b2e61a0c4474567dcf42cce9Ubuntu Security Notice 1074-2 - USN-1074-1 fixed vulnerabilities in linux-fsl-imx51 in Ubuntu 9.10. This update provides the corresponding updates for Ubuntu 10.04. Multiple vulnerabilities have been discovered and addressed in the Linux kernel. Al Viro discovered a race condition in the TTY driver. Dan Rosenberg discovered that the MOVE_EXT ext4 ioctl did not correctly check file permissions. Neil Brown discovered that NFSv4 did not correctly check certain write requests.

934d6a5d2bde45285650af4dbbaad8b2Mandriva 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.
b09673d46bd0c26aeac9afa523e5a306Mandriva Linux Security Advisory 2010-257 - The setup_arg_pages function in fs/exec.c in the Linux kernel before 2.6.36, when CONFIG_STACK_GROWSDOWN is used, does not properly restrict the stack memory consumption of the environment for a 32-bit application on a 64-bit platform, which allows local users to cause a denial of service via a crafted exec system call, a related issue to CVE-2010-2240. drivers/media/video/v4l2-compat-ioctl32.c in the Video4Linux implementation in the Linux kernel before 2.6.36 on 64-bit platforms does not validate the destination of a memory copy operation, which allows local users to write to arbitrary kernel memory locations, and consequently gain privileges, via a VIDIOCSTUNER ioctl call on a /dev/video device, followed by a VIDIOCSMICROCODE ioctl call on this device. Various other issues have been addressed as well.
cbebccc9f3a37f2a2a6720c5b935c95dDebian 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.
07b0d3c309caaad87815b6ce515a5e92Ubuntu Security Notice 1000-1 - Various image updates have been provided. Joel Becker discovered that OCFS2 did not correctly validate on-disk symlink structures. Al Viro discovered a race condition in the TTY driver. Dan Rosenberg discovered that the MOVE_EXT ext4 ioctl did not correctly check file permissions. Dan Rosenberg discovered that the swapexit xfs ioctl did not correctly check file permissions. Suresh Jayaraman discovered that CIFS did not correctly validate certain response packets. Various other issues have also been addressed.
