Description |
|
|
Se ha descubierto una vulnerabilidad en la versión 2.5 y anteriores de Squid. La vulnerabilidad reside en que Squid no genera un error fatal cuando detecta ACLs inválidas en la configuración http_access. Esta vulnerabilidad podría provocar que Squid arranque con unas ACLs menos restrictivas que las pretendidas por el administrador. |
