Debian Security Advisory

DSA-1175-1 isakmpd -- programming error

Date Reported:

13 Sep 2006

Affected Packages:

isakmpd

Vulnerable:

Yes

Security database references:

In the Debian bugtracking system: Bug 385894.
In the Bugtraq database (at SecurityFocus): BugTraq ID 19712.
In Mitre's CVE dictionary: CVE-2006-4436.

More information:

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.

Fixed in:

Debian GNU/Linux 3.1 (sarge)
