Linux Kernel 2.6.27.45

The robust futex implementation in the Linux kernel before 2.6.28 does not properly handle processes that make exec system calls, which allows local users to cause a denial of service or possibly gain privileges by writing to a memory location in a child process.

Linux kernel 2.6.18 through 2.6.33, and possibly other versions, allows remote attackers to cause a denial of service (memory corruption) via a large number of Bluetooth sockets, related to the size of sysfs files in (1) net/bluetooth/l2cap.c, (2) net/bluetooth/rfcomm/core.c, (3) net/bluetooth/rfcomm/sock.c, and (4) net/bluetooth/sco.c.

fs/namei.c in Linux kernel 2.6.18 through 2.6.34 does not always follow NFS automount "symlinks," which allows attackers to have an unknown impact, related to LOOKUP_FOLLOW.

Integer overflow in rose_sendmsg (sys/net/af_rose.c) in the Linux kernel 2.6.24.4, and other versions before 2.6.30-rc1, might allow remote attackers to obtain sensitive information via a large length value, which causes "garbage" memory to be sent.

mm/shmem.c in the Linux kernel before 2.6.28-rc8, when strict overcommit is enabled and CONFIG_SECURITY is disabled, does not properly handle the export of shmemfs objects by knfsd, which allows attackers to cause a denial of service (NULL pointer dereference and knfsd crash) or possibly have unspecified other impact via unknown vectors. NOTE: this vulnerability exists because of an incomplete fix for CVE-2010-1643.
