Des mises \u00e0 jour correctives ont \u00e9t\u00e9 formul\u00e9es pour toutes les branches prises en charge de PostgreSQL 17.1, 16.5, 15.9, 14.14, 13.17 et 12.21, corrigeant 35 erreurs et \u00e9liminant 3 vuln\u00e9rabilit\u00e9s \u2014 une critique et deux non critiques. Il a \u00e9galement \u00e9t\u00e9 annonc\u00e9 que la prise en charge de la branche PostgreSQL 12 est arr\u00eat\u00e9e, et il n'y aura plus de mises \u00e0 jour pour celle-ci. <\/p>\n
Une vuln\u00e9rabilit\u00e9 critique (CVE-2024-10979), not\u00e9e 8,8 sur 10, permet \u00e0 un utilisateur local de la base de donn\u00e9es, ayant les droits de cr\u00e9ation de fonctions PL\/Perl, d'ex\u00e9cuter du code avec les privil\u00e8ges de l'utilisateur sous lequel s'ex\u00e9cute la base de donn\u00e9es. Cette vuln\u00e9rabilit\u00e9 est due au fait que dans les fonctions PL\/Perl, il est possible de modifier les variables d'environnement du processus de travail, y compris la variable PATH, qui d\u00e9finit les chemins vers les fichiers ex\u00e9cutables, ainsi que des variables d'environnement sp\u00e9cifiques \u00e0 PostgreSQL. Il est \u00e0 noter que pour effectuer une attaque, un acc\u00e8s \u00e0 la base de donn\u00e9es est suffisant et aucun compte syst\u00e8me n'est requis.
