U radu programskog paketa HTTPD, namijenjenog operacijskom sustavu Fedora 15, uočeno je više sigurnosnih nedostataka. Napadač ih može iskoristiti za izvođenje DoS napada, pregled određenih podataka, stjecanje većih ovlasti i slanje zahtjeva intranet poslužiteljima.

2012-02-14 08:18:32
--------------------------------------------------------------------------------

Name        : httpd
Product     : Fedora 15
Version     : 2.2.22
Release     : 1.fc15
URL         : http://httpd.apache.org/
Summary     : Apache HTTP Server
Description :
The Apache HTTP Server is a powerful, efficient, and extensible
web server.

--------------------------------------------------------------------------------
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)
