Description Mark J. Cox 2008-02-21 18:44:07 UTC 
Whilst investigating a memory leak issue handling IPP browse requests (Bug
#433825) we discovered that older versions of CUPS as shipped with Enterprise
Linux 3 and 4 could end up derefencing free'd memory.

A malicious user on the local subnet could send a set of carefully crafted IPP
packets to the udp port in such a way as to cause CUPS to crash.

This issue doesn't affect recent upstream versions of CUPS as shipped in Red Hat
Enterprise Linux 5.
