Vulnerability from certfr_avis - Published: - Updated:

De multiples vulnérabilités ont été corrigées dans PostgreSQL, permettant notamment d'exécuter du code arbitraire à distance et de contourner la politique de sécurité.

Description

De multiples vulnérabilités ont été découvertes dans PostgreSQL :

  • les restrictions d'exécution des fonctions peuvent être contournées par les utilisateurs sous certaines conditions (CVE-2012-0866) ;
  • lorsque des certificats SSL sont utilisés, il est possible d'usurper un nom de machine si celui-ci fait exactement 32 caractères (CVE-2012-0867) ;
  • il est possible d'exécuter des commandes SQL via des noms d'objet spécifiques (CVE-2012-0868).

Solution

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