Patrick Webster has reported a vulnerability in Tumbleweed SecureTransport, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the SecureTransport FileTransfer ActiveX Control (e.g. vcst_eu.dll, vcst_en.dll) when handling arguments to the "TransferFile()" method. This can be exploited to cause a stack-based buffer overflow by passing an overly long "remoteFile" string to the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in vcst_eu.dll version 18.104.22.168. Other versions may also be affected.
Solution: Reportedly fixed in SecureTransport Server 4.6.1 Hotfix 20.
