Description:
Two weaknesses have been reported in DC++, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) A weakness is caused due to a NULL pointer dereference error when handling partial file list requests and can be exploited to cause the application to crash.
2) A weakness is caused due to an error within the "NmdcHub::onLine()" function in dcpp/dcpp/NmdcHub.cpp when processing private messages. This can be exploited to crash a client by sending private messages with an empty body.
The weaknesses are reported in versions prior to 0.707 (Unstable).
Solution:
The vendor has released version 0.707 (Unstable).
