Bulletin d'alerte Debian

DSA-1461-1 libxml2 -- Validations des entrées insuffisantes

Date du rapport :
13 janvier 2008
Paquets concernés :
libxml2
Vulnérabilité :
Oui
Références dans la base de données de sécurité :
Dans le dictionnaire CVE du Mitre : CVE-2007-6284.
Plus de précisions :

Brad Fitzpatrick a découvert que les fonctions de libxml2 décodant l'UTF-8, la bibliothèque XML de Gnome, ne vérifiaient pas suffisamment la validité des données UTF-8. Cela pourrait conduire à une déni de service en obligeant libxml2 à entrer dans une boucle sans fin.

Pour l'ancienne distribution stable (Sarge), ce problème a été corrigé dans la version 2.6.16-7sarge1.

Pour la distribution stable (Etch), ce problème a été corrigé dans la version 2.6.27.dfsg-2.

Pour la distribution instable (Sid), ce problème sera corrigé prochainement.

Nous vous recommandons de mettre à jour votre paquet libxml2.

Corrigé dans :

Debian GNU/Linux 3.1 (oldstable)
