DSA-986-1 gnutls11 -- Dépassements de tampon

Date du rapport :

6 mars 2006

Paquets concernés :

Vulnérabilité :

Oui

Références dans la base de données de sécurité :

Dans la base de données de suivi des bogues (chez SecurityFocus) : Identifiant BugTraq 16568.
Dans le dictionnaire CVE du Mitre : CVE-2006-0645.

Plus de précisions :

Evgeny Legerov a découvert plusieurs accès à la mémoire hors des limites dans le composant de décodage DER de la bibliothèque Tiny ASN.1, qui étaient aussi présents et utilisés dans GnuTLS, l'implémentation GNU des protocoles TLS 1.0 et SSL 3.0. Ces accès permettaient aux attaquants de planter le décodeur DER et peut-être d'exécuter du code arbitraire.

L'ancienne distribution stable (Woody) n'est pas touchée par ces problèmes.

Pour l'actuelle distribution stable (Sarge), ces problèmes ont été corrigés dans la version 1.0.16-13.2.

Pour la distribution instable (Sid), ces problèmes seront bientôt corrigés.

Nous vous recommandons de mettre à jour vos paquets gnutls.

Corrigé dans :

Debian GNU/Linux 3.1 (sarge)
