--------------------------------------------------------------------------------
Update Information:

This update contains the latest stable release of the Apace HTTP Server, version 2.2.22.  This release fixes various bugs, and the following security issues:

* Reject requests where the request-URI does not match the HTTP specification, preventing unexpected expansion of target URLs in some reverse proxy configurations. (CVE-2011-3368)

* Fix integer overflow in ap_pregsub() which, when the mod_setenvif module is enabled, could allow local users to gain privileges via a .htaccess file.  (CVE-2011-3607)

* Resolve additional cases of URL rewriting with ProxyPassMatch or RewriteRule, where particular request-URIs could result in undesired backend network exposure in some configurations.  (CVE-2011-4317)

* mod_log_config: Fix segfault (crash) when the '%{cookiename}C' log format string is in use and a client sends a nameless, valueless cookie, causing a denial of service. The issue existed since version 2.2.17.  (CVE-2012-0021)

* Fix scoreboard issue which could allow an unprivileged child process could cause the parent to crash at shutdown rather than terminate cleanly.  (CVE-2012-0031)

* Fixed an issue in error responses that could expose "httpOnly" cookies when no custom ErrorDocument is specified for status code 400.  (CVE-2012-0053)
