Vulnerability from certfr_avis - Published: - Updated:

Une vulnérabilité a été corrigée dans Asterisk Open Source et Business Edition. Elle permet à un utilisateur malintentionné d'exécuter du code arbitraire à distance.

Description

Une vulnérabilité a été corrigée dans Asterisk Open Source et Business Edition. Elle permet, lorsque le serveur est configuré en mode « pedantic », à un utilisateur malintentionné et préalablement authentifié d'exécuter du code arbitraire à distance au moyen d'une requête SIP sortante spécialement conçue.

Solution

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