Description:
keilh has reported a vulnerability in Apache 2 mod_ssl, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to a NULL pointer dereference error in mod_ssl. This can be exploited to crash Apache via a specially crafted request.
Successful exploitation requires that the server is using the non-default worker MPM, is configured with a SSL virtual host with access control, and using a custom 400 error document.
Do you have this product installed on your home computer? Scan using the free Personal Software Inspector. Check if a vulnerable version is installed on computers in your corporate network, scan using the Network Software Inspector.
