-
- *) mod_ssl: New directive SSLSessionTickets (On|Off).
- The directive controls the use of TLS session tickets (RFC 5077),
- default value is "On" (unchanged behavior).
- Session ticket creation uses a random key created during web
- server startup and recreated during restarts. No other key
- recreation mechanism is available currently. Therefore using session
- tickets without restarting the web server with an appropriate frequency
- (e.g. daily) compromises perfect forward secrecy. [Rainer Jung]

- out of date documentation. [William Rowe]
-
-Changes with Apache 2.2.28 (not released)
-
- *) SECURITY: CVE-2014-0118 (cve.mitre.org)
- mod_deflate: The DEFLATE input filter (inflates request bodies) now
- limits the length and compression ratio of inflated request bodies to avoid
- denial of service via highly compressed bodies. See directives
- DeflateInflateLimitRequestBody, DeflateInflateRatioLimit,
- and DeflateInflateRatioBurst. [Yann Ylavic, Eric Covener]
-
- *) SECURITY: CVE-2014-0231 (cve.mitre.org)
- mod_cgid: Fix a denial of service against CGI scripts that do
- not consume stdin that could lead to lingering HTTPD child processes
- filling up the scoreboard and eventually hanging the server. By
- default, the client I/O timeout (Timeout directive) now applies to
- communication with scripts. The CGIDScriptTimeout directive can be
- used to set a different timeout for communication with scripts.
- [Rainer Jung, Eric Covener, Yann Ylavic]
-
- *) SECURITY: CVE-2014-0226 (cve.mitre.org)
- Fix a race condition in scoreboard handling, which could lead to
- a heap buffer overflow. [Joe Orton, Eric Covener, Jeff Trawick]
-
- *) SECURITY: CVE-2013-5704 (cve.mitre.org)
- core: HTTP trailers could be used to replace HTTP headers
- late during request processing, potentially undoing or
- otherwise confusing modules that examined or modified
- request headers earlier. Adds "MergeTrailers" directive to restore
- legacy behavior. [Edward Lu, Yann Ylavic, Joe Orton, Eric Covener]
-
- *) core: Detect incomplete request and response bodies, log an error and
- forward it to the underlying filters. PR 55475. [Yann Ylavic]

- resumed by TLS session resumption (RFC 5077). [Rainer Jung]
-
- *) mod_proxy_ajp: Forward local IP address as a custom request attribute
- like we already do for the remote port. [Rainer Jung]
-
- *) mod_deflate: Don't fail when flushing inflated data to the user-agent

- buffer"). PR 56196. [Christoph Fausak <christoph fausak glueckkanja.com>]
-
- *) mod_cache, mod_disk_cache: With CacheLock enabled, responses with a Vary

- *) mod_rewrite: Support session cookies with the CO= flag when later
- parameters are used. The doc for this implied the feature had been

- [William Rowe, Ruediger Pluem, Jim Jagielski]
-
- *) SECURITY: CVE-2013-6438 (cve.mitre.org)
