(RHSA-2007:0533) Moderate: httpd security update

The Apache HTTP Server is a popular Web server.

A flaw was found in the Apache HTTP Server mod_status module. On sites
where the server-status page is publicly accessible and ExtendedStatus is
enabled this could lead to a cross-site scripting attack. On Red Hat
Enterprise Linux the server-status page is not enabled by default and it is
best practice to not make this publicly available. (CVE-2006-5752)

A flaw was found in the Apache HTTP Server mod_cache module. On sites where
caching is enabled, a remote attacker could send a carefully crafted
request that would cause the Apache child process handling that request to
crash. This could lead to a denial of service if using a threaded
Multi-Processing Module. (CVE-2007-1863)

In addition, two bugs were fixed:

• when the ProxyErrorOverride directive was enabled, responses with 3xx
  status-codes would be overriden at the proxy. This has been changed so that
  only 4xx and 5xx responses are overriden.

• the “ProxyTimeout” directive was not inherited across virtual host
  definitions.

Users of httpd should upgrade to these updated packages, which contain
backported patches to correct these issues. Users should restart Apache
after installing this update.
