Linux kernel af_netlink.c denial of service
| kernel-afnetlink-dos (24202) |  Low Risk |
Description:
Linux kernel is vulnerable to a denial of service caused by a vulnerability in af_netlink.c. A local attacker could set the nlmsg_len field to 0 to cause an infinite loop in the netlink_rcv_skb() function, resulting in a denial of service.
Platforms Affected:
- Linux, Kernel 2.6.14 rc4
- Linux, Kernel 2.6.14 rc3
- Linux, Kernel 2.6.14 rc1
- Linux, Kernel 2.6.14
- Linux, Kernel 2.6.14 rc2
- Linux, Kernel 2.6.14.1
- Linux, Kernel 2.6.14.2
- Linux, Kernel 2.6.14.3
- Linux, Kernel 2.6.14.4
- Linux, Kernel 2.6.15 rc2
- Linux, Kernel 2.6.15
- Linux, Kernel 2.6.15 rc1
- Linux, Kernel 2.6.15 rc7
- Linux, Kernel 2.6.15 rc6
- Linux, Kernel 2.6.15 rc5
- Linux, Kernel 2.6.15 rc4
- Linux, Kernel 2.6.15 rc3
Remedy:
Upgrade to the latest stable version of Linux Kernel (2.6.15.1 or later), available from The Linux Kernel Archives. See References.
Consequences:
Denial of Service
