The Apache Software Foundation and the Apache HTTP Server Project
are pleased to announce the release of version 2.4.9 of the Apache
HTTP Server ("Apache"). This version of Apache is our latest GA
release of the new generation 2.4.x branch of Apache HTTPD and
represents fifteen years of innovation by the project, and is
recommended over all previous releases. This release of Apache is
principally a security, feature and bug fix release.
Segfaults with truncated cookie logging.
mod_log_config: Prevent segfaults when logging truncated
cookies. Clean up the cookie logging parser to recognize
only the cookie=value pairs, not valueless cookies.
mod_dav: Keep track of length of cdata properly when removing
leading spaces. Eliminates a potential denial of service from
specifically crafted DAV WRITE requests
Also in this release are some exciting new features including:
*) Finer control over scoping of RewriteRules
*) Unix Domain Socket (UDS) support for mod_proxy backends.
*) Support for larger shared memory sizes for mod_socache_shmcb
*) mod_lua and mod_ssl enhancements
*) Support named groups and backreferences within the LocationMatch,
DirectoryMatch, FilesMatch and ProxyMatch directives.
We consider this release to be the best version of Apache available, and
encourage users of all prior versions to upgrade. [NOTE: 2.4.8 was not
