Vulnerability from certfr_avis - Published: 2011-08-24 - Updated: 2011-08-24

Des vulnérabilités dans Pidgin permettent notamment de réaliser un déni de service à distance.

Description

Plusieurs vulnérabilités ont été découvertes dans Pidgin :

  • certains caractères spécifiques utilisés dans les pseudonymes IRC peuvent provoquer un arrêt inopiné du client Pidgin lors des requêtes WHO ;
  • une mauvaise gestion des réponses HTTP 100 via le protocole MSN peut provoquer une tentative d'accès à une zone non autorisée de la mémoire ;
  • sous Windows, en cliquant sur un lien de type file:// reçu par message instantané, le client Pidgin tente d'exécuter le fichier.

Solution

Se référer aux bulletins de sécurité de l'éditeur pour l'obtention des correctifs (cf. section Documentation).

Pidgin versions antérieures à 2.10.0.
