DESCRIPTION:
A vulnerability has been discovered in CUPS, which can be exploited
by malicious people to cause a DoS (Denial of Service) or to
potentially compromise a vulnerable system.

The vulnerability is caused due to an error within the
"process_browse_data()" function when adding printers and classes.
This can be exploited to free the same buffer twice by sending
specially crafted browser packets to the UDP port on which cupsd is
listening (by default port 631/UDP).

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 1.3.5. Prior versions may
also be affected.

SOLUTION:
Update to version 1.3.6.
