Scientific Linux Security Update : httpd on SL5.x i386/x86_64

Medium Nessus Plugin ID 60754


The remote Scientific Linux host is missing one or more security updates.


CVE-2010-0408 httpd: mod_proxy_ajp remote temporary DoS

CVE-2010-0434 httpd: request header information leak

It was discovered that mod_proxy_ajp incorrectly returned an 'Internal Server Error' response when processing certain malformed requests, which caused the back-end server to be marked as failed in configurations where mod_proxy is used in load balancer mode. A remote attacker could cause mod_proxy to not send requests to back-end AJP (Apache JServ Protocol) servers for the retry timeout period (60 seconds by default) by sending specially crafted requests.

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 adds the following enhancement :

- with the updated openssl packages from RHSA-2010:0162 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#567980)

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.


Update the affected packages.
