Vulnerability from certfr_avis - Published: 2011-12-07 - Updated: 2011-12-07

Plusieurs vulnérabilités dans Opera permettent à un utilisateur malveillant de contourner la politique de sécurité et de lire des données sans droit.

Description

Plusieurs vulnérabilités affectent Opera :

  • la politique de séparation des domaines n'est pas correctement mise en pratique. Des scripts provenant d'un serveur web peuvent capter des informations sur l'activité de l'utilisateur avec d'autres sites web ;
  • la gestion des domaines présente une erreur qui permet le positionnement de cookies et des communications interdomaines illégitimes ;
  • une attaque par interposition est possible sur le protocole SSL/TLS.

Solution

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

Opera 11.x.
