Vulnerability from certfr_avis - Published: - Updated:

Plusieurs vulnérabilités dans OpenSSL permettent à une personne malintentionnée d'effectuer un déni de service à distance ou de contouner la politique de sécurité.

Description

Plusieurs vulnérabilités ont été découvertes dans OpenSSL :

  • une erreur dans la fonction ASN1_STRING_print_ex() permet de provoquer un arrêt inopiné de l'application (crash) ;
  • une vulnérabilité dans la gestion des erreurs permet dans certaines conditions de faire passer une fausse signature pour valide ;
  • une erreur dans la gestion des structures ANS1 mal formées permet de provoquer un arrêt inopiné de l'application (crash).
