Debian DSA-1175-1 : isakmpd - programming error

medium Nessus Plugin ID 22717

Synopsis

The remote Debian host is missing a security-related update.

Description

A flaw has been found in isakmpd, OpenBSD's implementation of the Internet Key Exchange protocol, that caused Security Associations to be created with a replay window of 0 when isakmpd was acting as the responder during SA negotiation. This could allow an attacker to re-inject sniffed IPsec packets, which would not be checked against the replay counter.

Solution

Upgrade the isakmpd package.

For the stable distribution (sarge) this problem has been fixed in version 20041012-1sarge1.
