Package : isakmpd
Vulnerability : programming error
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2006-4436
BugTraq ID : 19712
Debian Bug : 385894

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.

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

For the unstable distribution (sid) this problem has been fixed in
version 20041012-4

We recommend that you upgrade your isakmpd package.
