Updated CUPS packages fix denial of service



Security Advisory - RHSA-2003:275-07
Updated CUPS packages fix denial of service

Updated CUPS packages that fix a problem where CUPS can hang are now available.

CUPS is a print spooler.

Paul Mitcheson reported a situation where the CUPS Internet Printing
Protocol (IPP) implementation in CUPS versions prior to 1.1.19 would get
into a busy loop. This could result in a denial of service. In order to
exploit this bug an attacker would need to have the ability to make a TCP
connection to the IPP port (by default 631).

Users of CUPS are advised to install these updated packages, which contain
a backported security patch and are not vulnerable to this issue.

These packages also fix a problem with the LPD backend that could cause
jobs to be repeated.
