news 28 Posted July 14, 2009 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: httpd security update Advisory ID: RHSA-2009:1156-01 Product: Red Hat Application Stack Advisory URL: https://rhn.redhat.com/errata/RHSA-2009-1156.html Issue date: 2009-07-14 CVE Names: CVE-2009-1195 CVE-2009-1890 CVE-2009-1891 ===================================================================== 1. Summary: Updated httpd packages that fix multiple security issues are now available for Red Hat Application Stack v2. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: Red Hat Application Stack v2 for Enterprise Linux (v.5) - i386, x86_64 3. Description: The Apache HTTP Server is a popular Web server. A denial of service flaw was found in the Apache mod_proxy module when it was used as a reverse proxy. A remote attacker could use this flaw to force a proxy process to consume large amounts of CPU time. (CVE-2009-1890) A denial of service flaw was found in the Apache mod_deflate module. This module continued to compress large files until compression was complete, even if the network connection that requested the content was closed before compression completed. This would cause mod_deflate to consume large amounts of CPU if mod_deflate was enabled for a large file. (CVE-2009-1891) A flaw was found in the handling of the "Options" and "AllowOverride" directives used by the Apache HTTP Server. In configurations using the "AllowOverride" directive with certain "Options=" arguments, local users were not restricted from executing commands from a Server-Side-Include script as intended. (CVE-2009-1195) All httpd users should upgrade to these updated packages, which contain backported patches to correct these issues. After installing the updated packages, the httpd daemon must be restarted for the update to take effect. 4. Solution: Before applying this update, make sure that all previously-released errata relevant to your system have been applied. This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at http://kbase.redhat.com/faq/docs/DOC-11259 5.
