Summary: Updated httpd22 packages that fix multiple security issues are now available for JBoss Enterprise Web Server 1.0.0 for Red Hat Enterprise Linux 4. 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 4AS-JBEWS-5.0.0 - i386, x86_64 JBoss Enterprise Web Server 4ES-JBEWS-5.0.0 - i386, x86_64 3. Description: The Apache HTTP Server is a popular Web server. The httpd22 packages shipped with JBoss Enterprise Web Server 1.0.0 for Red Hat Enterprise Linux 4 contain an embedded copy of the Apache Portable Runtime (APR) utility library, a free library of C data structures and routines, which includes interfaces to support XML parsing, LDAP connections, database interfaces, URI parsing, and more. 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 apr-util Extensible Markup Language (XML) parser. A remote attacker could create a specially-crafted XML document that would cause excessive memory consumption when processed by the XML decoding engine. (CVE-2009-1955) A heap-based underwrite flaw was found in the way apr-util created compiled forms of particular search patterns. An attacker could formulate a specially-crafted search keyword, that would overwrite arbitrary heap memory locations when processed by the pattern preparation engine. (CVE-2009-0023) 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.
