DSA-821-1 python2.3 -- Dépassement d'entier

Date du rapport:

28 septembre 2005

Paquets concernés:

Vulnérabilité:

Oui

Références dans la base de données de sécurité:

Dans le système de suivi des bogues Debian : Bogue 324531.
Dans la base de données de suivi des bogues (chez SecurityFocus) : Identificateur BugTraq 14620.
Dans le dictionnaire CVE du Mitre : CVE-2005-2491.

Pour plus d'information:

Un dépassement d'entier pouvant entraîner un dépassement de tampon a été détecté dans PCRE, la bibliothèque « Perl Compatible Regular Expressions », qui permettait à un attaquant d'exécuter du code arbitraire. Cette bibliothèque est également présente dans Python. Les attaquants pouvaient exploiter cette vulnérabilité s'ils connaissaient l'expression régulière adéquate.

L'ancienne distribution stable (Woody) ne contient pas de paquet python2.3.

Pour l'actuelle distribution stable (Sarge), ce problème a été corrigé dans la version 2.3.5-3sarge1.

Pour la distribution instable (Sid), ce problème a été corrigé dans la version 2.3.5-8.

Nous vous recommandons de mettre à jour vos paquets python2.3

Corrigé dans:

Debian GNU/Linux 3.1 (sarge)
