1. Problem Description

        The Common Vulnerabilities and Exposures project (cve.mitre.org)
        has assigned the following names to these issues.

        CAN-2003-0192: Apache 2 before 2.0.47, and certain versions
        of mod_ssl for Apache 1.3, do not properly handle "certain
        sequences of per-directory re-negotiations and the
        SSLCipherSuite directive being used to upgrade from a weak
        cipher suite to a strong one," which could cause Apache
        to use the weak cipher suite. 

        CAN-2003-0542: Multiple stack-based buffer overflows in 
        mod_alias and mod_rewrite for Apache before 1.3.29 may allow 
        attackers to create configuration files to cause a denial of 
        service or execute arbitrary code via a regular expression
        with more than 9 captures.
