7fd5e9259774393a258a0c189d667e06ba833c9fb8b0cd11fa8fb35727aecafaUbuntu 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.
b470551b1de773c77d363adf5b0cb1910cc8654d0405c8a191ad8f00fd5d2535This 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.
2d37f538eada970a47c67a722a79c8dce6b69007ccd606d4168c8d3c2c9a2c21Ubuntu Security Notice 1186-1 - Dan Rosenberg discovered that IPC structures were not correctly initialized on 64bit systems. A local attacker could exploit this to read kernel stack memory, leading to a loss of privacy. Steve Chen discovered that setsockopt did not correctly check MSS values. A local attacker could make a specially crafted socket call to crash the system, leading to a denial of service. Vladymyr Denysov discovered that Xen virtual CD-ROM devices were not handled correctly. A local attacker in a guest could make crafted blkback requests that would crash the host, leading to a denial of service. Various other issues were also addressed.

4cde969b4cdb9c88d249a1bc077eb95b786a6396542e2655f3fdef84c6102638Mandriva 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.
