CVE-2009-1699

The XSL stylesheet implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle XML external entities, which allows remote attackers to read arbitrary files via a crafted DTD, as demonstrated by a file:///etc/passwd URL in an entity declaration, related to an "XXE attack."

The XSL stylesheet implementation in WebKit in Apple Safari before 4.0, iPhone OS 1.0 through 2.2.1, and iPhone OS for iPod touch 1.1 through 2.2.1 does not properly handle XML external entities, which allows remote attackers to read arbitrary files via a crafted DTD, as demonstrated by a file:///etc/passwd URL in an entity declaration, related to an "XXE attack."

La implementación de la hoja de estilo XSL en WebKit en Apple Safari anterior a v4.0 no maneja adecuadamente las entidades externas XML, lo cual permite a atacantes remotos leer ficheros arbitrarios a través de un DTD elaborado, como lo demuestra un fichero: ///etc/passwd URL en una declaración de entidad, relacionado con un "ataque XXE".
