DESCRIPTION OF THE VULNERABILITY

Two denials of service were announced in Apache httpd.

The mod_proxy_ajp module is used with Tomcat. When the client uses the Content-Length header, but does not send a body, the ap_proxy_ajp_request() function returns the error HTTP_INTERNAL_SERVER_ERROR, instead of HTTP_BAD_REQUEST. A timeout is then started, which creates a denial of service. [severity:2/4; BID-38491, CVE-2010-0408]

The mod_isapi module is used on Windows. However, by interrupting a query, this module is unloaded too soon, which forces the usage of an invalid pointer, and stops the service. [severity:2/4; CVE-2010-0425, SOS-10-002]
