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)
