Linux kernel ip_options_get denial of service
| linux-ipoptionsget-dos (18522) |  Low Risk |
Description:
Linux kernel is vulnerable to an integer overflow 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.
Consequences:
Denial of Service
