The httpd packages provide the Apache HTTP Server, a powerful, efficient,and extensible web server.It was found that the mod_dav module did not correctly strip leading whitespace from certain elements in a parsed XML. In certain httpdconfigurations that use the mod_dav module (for example when using themod_dav_svn module), a remote attacker could send a specially crafted DAVrequest that would cause the httpd child process to crash or, possibly,allow the attacker to execute arbitrary code with the privileges of the"apache" user. (CVE-2013-6438)A buffer over-read flaw was found in the httpd mod_log_config module.In configurations where cookie logging is enabled (on Red Hat EnterpriseLinux it is disabled by default), a remote attacker could use this flaw tocrash the httpd child process via an HTTP request with a malformed cookieheader. (CVE-2014-0098)All httpd users are advised to upgrade to these updated packages, whichcontain backported patches to correct these issues. After installing theupdated packages, the httpd daemon will be restarted automatically.
