Dans le patch gssapi.patch utilis\u00e9 dans de nombreuses distributions Linux, qui ajoute la prise en charge de l'\u00e9change de cl\u00e9s bas\u00e9 sur GSSAPI dans OpenSSH, une vuln\u00e9rabilit\u00e9 a \u00e9t\u00e9 d\u00e9tect\u00e9e, entra\u00eenant une corruption de la m\u00e9moire et un contournement du m\u00e9canisme de s\u00e9paration des privil\u00e8ges.

La vuln\u00e9rabilit\u00e9 se manifeste lors de l'activation de l'option \u00ab GSSAPIKeyExchange yes \u00bb dans les param\u00e8tres.<\/p>\n

Il est remarquable que, \u00e0 l'\u00e9poque, les d\u00e9veloppeurs d'OpenSSH ont refus\u00e9 d\u2019accepter la modification pour prendre en charge GSSAPI, car des doutes sur sa s\u00e9curit\u00e9 ont \u00e9t\u00e9 soulev\u00e9s. Cependant, de nombreuses distributions Linux ont inclus ce patch dans leurs paquets OpenSSH.<\/p>\n
