Symantec Messaging Gateway version 9.5.3-3 suffers from backdoor account and privilege escalation vulnerabilities.
0037358302ea3ef9e579ea39b29f6aeedaab8ea3fd730436e1fe43363d09f8dcThis exploit leverages three vulnerabilities to escalate privileges. The primary vulnerability is a kernel stack overflow, not a stack buffer overflow as the CVE description incorrectly states. This may be the first public exploit for a kernel stack overflow, and it turns out to be a bit tricky due to some particulars of the econet vulnerability. It involves the econet_sendmsg function, ec_dev_ioctl function, and the ipc subsystem. Linux kernel versions prior to 2.6.36.2 are affected.

ee2b27059547517c9b31d6346cedd7eacba9014e9eeb821192ed01e86e778b49Ubuntu 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.

4cde969b4cdb9c88d249a1bc077eb95b786a6396542e2655f3fdef84c6102638Mandriva 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.
1e230666cbb1fc66c91156a8035fbdbdaca4fbe40c2a8ed95fd1ecd43722fa30Linux kernel local privilege escalation exploit for versions 2.6.37 and below. It leverages three separate vulnerabilities to achieve root including a NULL pointer dereference, being able to assign arbitrary Econet addresses to arbitrary interfaces, and the ability to write a NULL word to an arbitrary kernel address.
90c6bf981c13631f20aedf98e74ee2ce76bde194f9c594a64c300a938f3bfa47Ubuntu Security Notice 1023-1 - Nelson Elhage discovered several problems with the Acorn Econet protocol driver. A local user could cause a denial of service via a NULL pointer dereference, escalate privileges by overflowing the kernel stack, and assign Econet addresses to arbitrary interfaces.
