Vulnerability from certfr_avis

Plusieurs vulnérabilités dans le système d'exploitation Cisco IOS permettent à un utilisateur malveillant de provoquer un déni de service à distance ou de contourner la politique de sécurité.

Description

Un utilisateur malveillant peut :

  • provoquer un déni de service à distance au moyen de communications IRC, de flux SIP, de changements de numéro unique (SNR) ou d'annonces de routeurs en IPv6 ;
  • contourner la politique de sécurité en raison d'une erreur dans la gestion des clefs publiques.

Solution
