A vulnerability has been discovered in SSReader, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error in the Pdg2 ActiveX control (pdg2.dll) when handling arguments passed to the "Register()" method. This can be exploited to cause a stack-based buffer overflow by passing an overly long (greater than 256 bytes) argument to the affected method.
Successful exploitation allows execution of arbitrary code.
The vulnerability is confirmed in SSReader version 4.0. Other versions may also be affected.
Solution: Set the kill-bit for the affected ActiveX control.
Provided and/or discovered by: Discovered as a 0-day.
