-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: cups-filters security, bug fix, and enhancement update Advisory ID: RHSA-2015:2360-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-2360.html Issue date: 2015-11-19 CVE Names: CVE-2015-3258 CVE-2015-3279 ===================================================================== 1. Summary: Updated cups-filters packages that fix two security issues, several bugs, and add one enhancement are now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having Moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode (v. 7) - x86_64 Red Hat Enterprise Linux ComputeNode Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - aarch64, ppc64, ppc64le, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (v. 7) - x86_64 3. Description: The cups-filters packages contain back ends, filters, and other software that was once part of the core Common UNIX Printing System (CUPS) distribution but is now maintained independently. A heap-based buffer overflow flaw and an integer overflow flaw leading to a heap-based buffer overflow were discovered in the way the texttopdf utility of cups-filter processed print jobs with a specially crafted line size. An attacker able to submit print jobs could use these flaws to crash texttopdf or, possibly, execute arbitrary code with the privileges of the "lp" user. (CVE-2015-3258, CVE-2015-3279) The CVE-2015-3258 issue was discovered by Petr Sklenar of Red Hat. Notably, this update also fixes the following bug: * Previously, when polling CUPS printers from a CUPS server, when a printer name contained an underscore (_), the client displayed the name containing a hyphen (-) instead. This made the print queue unavailable. With this update, CUPS allows the underscore character in printer names, and printers appear as shown on the CUPS server as expected. (BZ#1167408) In addition, this update adds the following enhancement: * Now, the information from local and remote CUPS servers is cached during each poll, and the CUPS server load is reduced. (BZ#1191691) All cups-filters users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied.
