Description:
CelebrityHacker has discovered a vulnerability in Altnet Download Manager, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the "IsValidFile()" method in the ADM ActiveX control. This can be exploited to cause a stack-based buffer overflow via e.g. a malicious web site by passing an overly long string to the "bstrFilepath" parameter.
Successful exploitation may allow execution of arbitrary code.
The vulnerability has been confirmed on Altnet Download Manager 4.0.0.2 and 4.0.0.4. Other versions may also be affected.
NOTE: The application is included in the file-sharing applications Kazaa and Grokster.
Solution:
The vendor has issued an updated version.
