Vulnerability from certfr_avis - Published: - Updated:

Une vulnérabilité dans le moteur d'antivirus de Sophos permet à un utilisateur malintentionné de contourner la politique de sécurité.

Description

La gestion des fichiers d'archives (CAB, RAR, LZH) avec en-têtes malformés est imparfaite. Une vulnérabilité permet à un utilisateur malveillant de dissimuler au moteur d'antivirus un programme malveillant contenu dans une archive spécialement construite.
