The remote Scientific Linux host is missing one or more security
The Apache HTTP Server is a popular web server.
It was discovered that the Apache HTTP Server did not properly
validate the request URI for proxied requests. In certain
configurations, if a reverse proxy used the ProxyPassMatch directive,
or if it used the RewriteRule directive with the proxy flag, a remote
attacker could make the proxy connect to an arbitrary server, possibly
disclosing sensitive information from internal web servers not
directly accessible to the attacker. (CVE-2011-3368)
It was discovered that mod_proxy_ajp incorrectly returned an 'Internal
Server Error' response when processing certain malformed HTTP
requests, which caused the back-end server to be marked as failed in
configurations where mod_proxy was used in load balancer mode. A
remote attacker could cause mod_proxy to not send requests to back-end
AJP (Apache JServ Protocol) servers for the retry timeout period or
until all back-end servers were marked as failed. (CVE-2011-3348)
This update also fixes the following bug :
- The fix for CVE-2011-3192 provided by a previous update
introduced regressions in the way httpd handled certain
Range HTTP header values. This update corrects those
All httpd users should upgrade to these updated packages, which
contain backported patches to correct these issues. After installing
the updated packages, the httpd daemon must be restarted for the
update to take effect.
