Vulnerability from certfr_avis

Une vulnérabilité dans Cisco IOS XR permet de réaliser un déni de service à distance.

Description

Une vulnérabilité a été découverte dans la gestion des préfixes BGP par Cisco IOS XR. Un appareil utilisant Cisco IOS XR, qui reçoit un préfixe BGP avec un attribut transitif spécifique, va corrompre cet attribut avant de le réémettre à ses voisins. Les voisins peuvent alors réinitialiser la session BGP.

Solution

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

Tous les matériels avec le logiciel Cisco IOS XR configuré pour le routage BGP.

CWE

Summary

Cisco IOS XR 3.4.0 through 3.9.1, when BGP is enabled, does not properly handle unrecognized transitive attributes, which allows remote attackers to cause a denial of service (peering reset) via a crafted prefix announcement, as demonstrated in the wild in August 2010 with attribute type code 99, aka Bug ID CSCti62211.
