Rapporteret den:

9. feb 2001

Berørte pakker:

ssh

Sårbar:

Referencer i sikkerhedsdatabaser:

I Bugtraq-databasen (hos SecurityFocus): BugTraq-id 2344.
I Mitres CVE-ordbog: CVE-2001-0361.

Yderligere oplysninger:

Versioner af OpenSSH før 2.3.0 er sårbare overfor et fjernangreb hvor vilkårlig hukommelse bliver overskrevet, hvilket kan resultere i et root-angreb.
CORE-SDI har beskrevet problemet med hensyn til RSA-nøgleudveksling og et Bleichenbacher-angreb der opfanger sessionsnøglen fra en SSH-session.

Begge disse problemer er rettet i vores ssh-pakke 1.2.3-9.2. Vi anbefaler at du omgående opgraderer din openssh-pakke.
