Linux kernel ip_options_get memory leak
| linux-ipoptionsget-memory-leak (18524) |  Low Risk |
Description:
Linux kernel is vulnerable to a memory leak in the ip_options_get function. A local attacker could exploit this vulnerability to cause the kernel to crash.

Remedy:
For Linux kernel 2.6.x:
Upgrade to the latest version of Linux kernel (2.6.10rc3bk5 or later), available from the Linux kernel Web site. See References.
For Ubuntu Linux:
Upgrade to the latest linux-image package (2.6.8.1-16.5 or later), as listed in USN-47-1 December 23, 2004 for more information. See References.
For Red Hat Linux:
Upgrade to the latest kernel package, as listed below. Refer to Red Hat Security Advisory RHSA-2004:689-06, RHSA-2005:016-13, or RHSA-2005:017-14 for more information. See References.
For Debian GNU/Linux:
Refer to DSA-1070-1, DSA-1069-1, DSA-1067-1, or DSA-1082-1 for patch, upgrade, or suggested workaround information. See References.
For other distributions:
Contact your vendor for upgrade or patch information.
Consequences:
Denial of Service
