shinnai has discovered a vulnerability in IDAutomation Linear Barcode ActiveX Control, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error within the Linear BarCode ActiveX control (IDAutomationLinear6.dll) when handling the "SaveEnhWMF()" method. This can be exploited to cause a stack-based buffer overflow by passing an overly long argument to the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in version 220.127.116.11. Other versions may also be affected.
Solution: Update to the latest versions.
