Marc Stern discovered a buffer overflow in the SSL module’s certificate revocation list (CRL) handler. If Apache is configured to use a malicious CRL, this could possibly lead to a server crash or arbitrary code execution with the privileges of the Apache web server. (CAN-2005-1268)
Watchfire discovered that Apache insufficiently verified the “Transfer-Encoding” and “Content-Length” headers when acting as an HTTP proxy. By sending a specially crafted HTTP request, a remote attacker who is authorized to use the proxy could exploit this to bypass web application firewalls, poison the HTTP proxy cache, and conduct cross-site scripting attacks against other proxy users.
