Scientific Linux Security Update : httpd on SL4.x i386/x86_64
Medium Nessus Plugin ID 60753
SynopsisThe remote Scientific Linux host is missing one or more security updates.
DescriptionCVE-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.
SolutionUpdate the affected packages.
