It was found that the mod_dav module did not correctly strip leading white space from certain elements in a parsed XML. In certain httpd configurations that use the mod_dav module , a remote attacker could send a specially crafted DAV request 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. A buffer over-read flaw was found in the httpd mod_log_config module. In configurations where cookie logging is enabled, a remote attacker could use this flaw to crash the httpd child process via an HTTP request with a malformed cookie header
