CVE-2010-0434 httpd: request header information leak

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: 

After installing the updated packages, the httpd daemon must be 
restarted for the update to take effect.
