CVE-2009-0949: Null Pointer Dereference

First published: Fri May 15 2009(Updated: )

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.
