Overview
Some IPComp implementations may contain a kernel memory corruption vulnerability in their handling of nested encapsulation of IPComp payloads.
Description
RFC 3173 defines the IP Payload Compression Protocol (IPComp) as: IP payload compression is a protocol to reduce the size of IP datagrams. This protocol will increase the overall communication performance between a pair of communicating hosts/gateways ("nodes") by compressing the datagrams, provided the nodes have sufficient computation power, through either CPU capacity or a compression coprocessor, and the communication is over slow or congested links. |
Impact
A remote attacker can cause a kernel stack overflow leading to a denial of service or possibly execute arbitrary code. |
Solution
Apply a Patch from Your Vendor |
|
Vendor Information
Note that any systems derived from the KAME or NetBSD IPComp implementations may be vulnerable. |
