4) Description of Vulnerability

Secunia Research has discovered a vulnerability in Orbit Downloader, which can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when generating the "Connecting" log message for HTTP downloads. This can be exploited to cause a stack-based buffer overflow by e.g. tricking a user into downloading from a malicious HTTP server or opening a specially crafted HTTP URL containing an overly long host name.
