"From Red Hat Security Advisory 2010:0175 :

Updated httpd packages that fix one security issue, a bug, and add an
enhancement are now available for Red Hat Enterprise Linux 4.

The Red Hat Security Response Team has rated this update as having low
security impact. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available from the
CVE link in the References section.

The Apache HTTP Server is a popular web server.

A use-after-free flaw was discovered in the way the Apache HTTP Server
handled request headers in subrequests. In configurations where
subrequests are used, a multithreaded MPM (Multi-Processing Module)
could possibly leak information from other requests in request
replies. (CVE-2010-0434)

This update also fixes the following bug :

* a bug was found in the mod_dav module. If a PUT request for an
existing file failed, that file would be unexpectedly deleted and a
'Could not get next bucket brigade' error logged. With this update,
failed PUT requests no longer cause mod_dav to delete files, which
resolves this issue. (BZ#572932)

As well, this update adds the following enhancement :

* with the updated openssl packages from RHSA-2010:0163 installed,
mod_ssl will refuse to renegotiate a TLS/SSL connection with an
unpatched client that does not support RFC 5746. This update adds the
'SSLInsecureRenegotiation' configuration directive. If this directive
is enabled, mod_ssl will renegotiate insecurely with unpatched
clients. (BZ#575805)

Refer to the following Red Hat Knowledgebase article for more details
about the changed mod_ssl behavior:
http://kbase.redhat.com/faq/docs/DOC-20491

All httpd users should upgrade to these updated packages, which
contain backported patches to correct these issues and add this
enhancement. After installing the updated packages, the httpd daemon
must be restarted for the update to take effect."
