Referencer i sikkerhedsdatabaser:

I Debians fejlsporingssystem: Fejl 385894.
I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 19712.
I Mitres CVE-ordbog: CVE-2006-4436.

Yderligere oplysninger:

En fejl er fundet i isakmpd, OpenBSD's implementering af protokollen Internet Key Exchange, hvilket forårsagede at Security Associations blev oprettet med et replay-vindue på 0 når isakmpd fungerede som den svarende part i en SA-forhandling. Dette kunne gøre det muligt for en angriber at genindsprøjte opsnusede IPsec-pakker, der ikke blev kontrolleret mod replay-tælleren.

I den stabile distribution (sarge) er dette problem rettet i version 20041012-1sarge1.

I den ustabile distribution (sid) er dette problem rettet i version 20041012-4.

Vi anbefaler at du opgraderer din isakmpd-pakke.

Rettet i:

Debian GNU/Linux 3.1 (sarge)
