Red Hat: 2010:0175-01: httpd: Low Advisory
Summary
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:
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.
Summary
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
