Description

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

"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:
http://kbase.redhat.com/faq/docs/DOC-20491

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