Vulnerability from certfr_avis - Published: - Updated:

Plusieurs vulnérabilités affectent le traitement BGP de Cisco IOS XR et permettent à un utilisateur malveillant de provoquer un déni de service à distance.

Description

Plusieurs vulnérabilités affectent le traitement BGP de Cisco IOS XR :

le traitement défectueux d'un message BGP anormalement long de mise à jour de routage provoque un arrêt inopiné du processus BGP. Ce défaut permet à un utilisateur malveillant de provoquer un déni de service à distance ;
le traitement défectueux d'un message BGP de mise à jour de routage malformé provoque un arrêt de la négociation BGP. Ce défaut permet à un utilisateur malveillant de provoquer un déni de service à distance ;
le traitement défectueux d'un message BGP de mise à jour de routage avec un nombre élevé d'AS provoque un arrêt inopiné du processus BGP. Ce défaut permet à un utilisateur malveillant de provoquer un déni de service à distance.

Solution

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