Linux kernel sock_dgram_sendmsg race condition
| linux-sockdgramsendmsg-race-condition (18312) |  Low Risk |
Description:
Linux kernel is vulnerable to a denial of service attack, caused by a race condition. The sock_dgram_sendmsg function fails to properly handle SOCK_SEQPACKET unix domain sockets, which could allow a local attacker to cause the kernel to crash.
Consequences:
Denial of Service
Remedy:
Apply the patch for this vulnerability, as listed in the Linux-kernel Mailing List posting dated 2004-11-14 18:13:11. See References.
For Ubuntu Linux:
Upgrade to the latest linux-image package (2.6.8.1-16.3 or later), as listed in USN-38-1 December 14, 2004 for more information. See References.
For Gentoo Linux:
Upgrade to the latest version of cups (1.1.23_rc1 or later), as listed in GLSA 200412-25. See References.
For other distributions:
Contact your vendor for upgrade or patch information.
