Description

A flaw was found in LibVNCServer. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by sending specially crafted HTTP requests. The flaw exists in the HTTP proxy handlers, where missing validation of certain return values can lead to a null pointer dereference, causing the server to crash. This impacts the availability of the server when HTTPD and proxy features are enabled.
