Vulnerability Name:

CCN-66518

Published:2011-04-01
Updated:2011-04-01
Summary:NetBSD and FreeBSD are vulnerable to a stack-based buffer overflow, caused by improper bounds checking when handling certain IPComp (IP Payload Compression Protocol) payloads. By sending specially-crafted packets, a remote attacker could overflow a buffer and execute arbitrary code on the system or cause the application to crash.
