Se ha descubierto una vulnerabilidad en la versión 2.5 y anteriores de Squid. La vulnerabilidad reside en que el significado de los controles de acceso es confuso cuando alguna de las ACLs (access control lists) referenciadas es declarada vacía. La explotación de esta vulnerabilidad podría permitir a un atacante remoto evitar el control de ACLs. |
