multiple vulnerabilities, upgraded to apache-1.3.29
Advisory number: SCOSA-2004.6

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.
