Description Mark J. Cox 2008-02-21 16:44:05 UTC
Whilst investigating a double-free issue in process_browse_data (Bug #433758) we
discovered that older versions of CUPS as shipped with Enterprise Linux 3 and 4
did not free the mime type allocated when a remote resource timed out.

A malicious user on the local subnet could send carefully crafted IPP packets to
the udp port in such a way as to consume memory and lead to a CUPS crash.
