Description:
Elazar Broad has discovered a vulnerability in Lycos FileUploader Module, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the FileUploader.FUploadCtl.1 ActiveX control (FileUploader.dll) when handling strings assigned to the "HandwriterFilename" property. This can be exploited to cause a heap-based buffer overflow by assigning an overly-long string to the affected property.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in FileUploader.dll version 2.0.0.2. Other versions may also be affected.
Solution:
Set the kill-bit for the affected ActiveX control.
