CVE-2009-0949

The ippReadIO function in cups/ipp.c in cupsd in CUPS before 1.3.10 does not properly initialize memory for IPP request packets, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via a scheduler request with two consecutive IPP_TAG_UNSUPPORTED tags.

La función ippReadIO en cups/ipp.c en cupsd en CUPS antes de la versión 1.3.10 no inicia de manera apropiada la memoria para paquetes de solicitud IPP, lo que permite a atacantes remotos provocar una denegación de servicio (referencia a puntero nulo y caída del demonio) mediante una solicitud de programación (scheduler) con dos etiquetas IPP_TAG_UNSUPPORTED consecutivas.
