Includes the Apache Portable Runtime (APR) version 1.4.5 and APR Utility Library (APR-util) version 1.4.2.
This release builds on and extends the Apache 2.0 API.
SECURITY: Reject requests where the request-URI does not match the HTTP specification, preventing unexpected expansion of target URLs in some reverse proxy configurations.
SECURITY: 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.
SECURITY: Resolve additional cases of URL rewriting with ProxyPassMatch or RewriteRule, where particular request-URIs could result in undesired backend network exposure in some configurations.
SECURITY: 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.
SECURITY: Fix scoreboard issue which could allow an unprivileged child process could cause the parent to crash at shutdown rather than terminate cleanly.
SECURITY: Fixed an issue in error responses that could expose “httpOnly” cookies when no custom ErrorDocument is specified for status code 400.
