CVE-2007-2519

Vulnerabilidad de salto de directorio en el instalador en PEAR 1.0 hasat 1.5.3 permite a atacantes remotos con la intervención del usuario sobrescribir archivos de su elección mediante una secuencia .. (punto punto) en (1) el atributo install-as en el elemento fichero (file) en package.xml 1.0 o (2) el atributo as en el elemento instación (install) en package.xml 2.0. NOTA: podría argumentarse que esto no cruza los límites de privilegios en instalaciones típicas, puesto que el código que está siendo instalado podría realizar las mismas acciones.
