DSA-976-1 libast -- Dépassement de tampon

Date du rapport:

15 février 2006

Paquets concernés:

libast, libast1

Vulnérabilité:

Oui

Références dans la base de données de sécurité:

Dans le dictionnaire CVE du Mitre : CVE-2006-0224.

Pour plus d'information:

Johnny Mast a découvert un dépassement de tampon dans libast (the library of assorted spiffy things), qui pouvait permettre l'exécution de code arbitraire. Cette bibliothèque est utilisée par eterm qui est installé en modes setgid et setuid, ouvrant la porte à une vulnérabilité permettant la modification du fichier utmp.

Pour l'ancienne distribution stable (Woody), ces problèmes ont été corrigés dans la version 0.4-3woody2.

Pour l'actuelle distribution stable (Sarge), ces problèmes ont été corrigés dans la version 0.6-0pre2003010606sarge1.

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

Nous vous recommandons de mettre à jour vos paquets libast.

Corrigé dans:

Debian GNU/Linux 3.0 (woody)
