RHSA-2007:0533 - Security Advisory

Synopsis

Moderate: httpd security update

Type/Severity

Security Advisory: Moderate

Topic

Updated Apache httpd packages that correct two security issues and two bugs
are now available for Red Hat Enterprise Linux 3.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

Description

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.
