Summary: Updated httpd packages that fix multiple security issues are now available for JBoss Enterprise Web Server 1.0.0 for Red Hat Enterprise Linux 5. This update has been rated as having important security impact by the Red Hat Security Response Team. 2. Relevant releases/architectures: JBoss Enterprise Web Server 5Server-JBEWS-5.0.0 - 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 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) 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) All users of JBoss Enterprise Web Server 1.0.0 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. Bugs fixed (http://bugzilla.redhat.com/): 489436 - CVE-2009-1195 AllowOverride Options=IncludesNoExec allows Options Includes 509125 - CVE-2009-1891 httpd: possible temporary DoS (CPU consumption) in mod_deflate 509375 - CVE-2009-1890 httpd: mod_proxy reverse proxy DoS (infinite loop) 6.
