Descripción
Se ha descubierto una vulnerabilidad en la versión 1.1.19 de CUPS. La vulnerabilidad reside en que CUPS distingue entre mayúsculas y minúsculas en el nombre de la impresora a la hora de decidir que política de autorización de las definidas en el archivo "cupsd.conf" debe usar. Sin embargo, CUPS no distingue entre mayúsculas y minúsculas a la hora de identificar a una impresora. La explotación de esta vulnerabilidad podría permitir a un atacante remoto utilizar una impresora protegida con contraseña sin necesidad de autenticarse.
Solución
Si lo desea, aplique los mecanismos de actualización propios de su distribución, o bien baje las fuentes del software y compílelo usted mismo.
