3. Description:
The Apache HTTP Server is a popular Web server.
A flaw was found in the mod_proxy Apache module. An attacker in control of
a Web server to which requests were being proxied could have caused a
limited denial of service due to CPU consumption and stack exhaustion.
(CVE-2008-2364)
A flaw was found in the mod_proxy_ftp Apache module. If Apache was
configured to support FTP-over-HTTP proxying, a remote attacker could have
performed a cross-site scripting attack. (CVE-2008-2939)
In addition, these updated packages fix a bug found in the handling of the
"ProxyRemoteMatch" directive in the Red Hat Enterprise Linux 4 httpd
packages. This bug is not present in the Red Hat Enterprise Linux 3 or Red
Hat Enterprise Linux 5 packages.
Users of httpd should upgrade to these updated packages, which contain
backported patches to correct these issues.
4. Solution:
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
