DSA-1935-1 gnutls13 gnutls26 -- Plusieurs vulnérabilités

Date du rapport :

17 novembre 2009

Paquets concernés :

Vulnérabilité :

Oui

Références dans la base de données de sécurité :

Dans le système de suivi des bogues Debian : Bogue 541439.
Dans le dictionnaire CVE du Mitre : CVE-2009-2409, CVE-2009-2730.

Plus de précisions :

Dan Kaminsky et Moxie Marlinspike ont découvert que GnuTLS, une implémentation du protocole TLS/SSL, ne traite pas correctement un caractère \0 d'un nom de domaine dans les champs Common Name (CN) ou Subject Alternative Name (SAN) du sujet d'un certificat X.509. Cela permet aux attaquants en homme au milieu de se faire passer pour des serveurs SSL arbitraires à l'aide d'un certificat contrefait délivré par une autorité de certification légitime CVE-2009-2730).

De plus, avec cette mise à jour, les certificats avec des signatures de hachage MD2 ne sont plus acceptés puisqu'ils ne sont plus considérés sûrs d'un point de vue cryptographique. Cela ne concerne que la distribution oldstable (Etch) (CVE-2009-2409).

Pour la distribution oldstable (Etch), ces problèmes ont été corrigés dans la version 1.4.4-3+etch5 pour gnutls13.

Pour la distribution stable (Lenny), ces problèmes ont été corrigés dans la version 2.4.2-6+lenny2 pour gnutls26.

Pour la distribution testing (Squeeze) et la distribution unstable (Sid), ces problèmes ont été corrigés dans la version 2.8.3-1 pour gnutls26.

Nous vous recommandons de mettre à jour vos paquets gnutls13/gnutls26.
