Fedora Update Notification
FEDORA-2005-908
2005-09-22
---------------------------------------------------------------------

Product : Fedora Core 3
Name : cups
Version : 1.1.22
Release : 0.rc1.8.7
Summary : Common Unix Printing System
Description :
The Common UNIX Printing System provides a portable printing layer for
UNIX operating systems. It has been developed by Easy Software Products
to promote a standard printing solution for all UNIX vendors and users.
CUPS provides the System V and Berkeley command-line interfaces.

---------------------------------------------------------------------
Update Information:

A bug was found in the way CUPS processes malformed HTTP
requests. It is possible for a remote user capable of
connecting to the CUPS daemon to issue a malformed HTTP GET
request which will cause CUPS to enter an infinite loop.
This is CAN-2005-2874.
