-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 - --------------------------------------------------------------------- Red Hat Security Advisory Synopsis: Moderate: cups security update Advisory ID: RHSA-2005:772-01 Advisory URL: https://rhn.redhat.com/errata/RHSA-2005-772.html Issue date: 2005-09-27 Updated on: 2005-09-27 Product: Red Hat Enterprise Linux CVE Names: CAN-2005-2874 - --------------------------------------------------------------------- 1. Summary: Updated CUPS packages that fix a security issue are now available for Red Hat Enterprise Linux. This update has been rated as having moderate security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Enterprise Linux AS version 4 - i386, ia64, ppc, s390, s390x, x86_64 Red Hat Enterprise Linux Desktop version 4 - i386, x86_64 Red Hat Enterprise Linux ES version 4 - i386, ia64, x86_64 Red Hat Enterprise Linux WS version 4 - i386, ia64, x86_64 3. Problem description: The Common UNIX Printing System (CUPS) provides a portable printing layer for UNIX(R) operating systems. 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 that causes CUPS to enter an infinite loop. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2005-2874 to this issue. Two small bugs have also been fixed in this update. A signal handling problem has been fixed that could occasionally cause the scheduler to stop when told to reload. A problem with tracking open file descriptors under certain specific circumstances has also been fixed. All users of CUPS should upgrade to these erratum packages, which contain a patch to correct this issue. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. Use Red Hat Network to download and update your packages. To launch the Red Hat Update Agent, use the following command: up2date For information on how to install packages manually, refer to the following Web page for the System Administration or Customization guide specific to your system: http://www.redhat.com/docs/manuals/enterprise/ 5. Bug IDs fixed (http://bugzilla.redhat.com/): 164641 - [PATCH] cupsd segfault when SIGCHLD received 164642 - Cupsd hangs on reading pipe with recycled file descriptor. 168072 - CAN-2005-2874 Malformed HTTP Request URL denial of service 6.
