This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of IBM Lotus Quickr for Domino. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The flaw exists within an ActiveX control included in QP2.dll. The specific flaw is a stack buffer overflow in a vulnerable function in the control. By passing an overly long value into a property, and then triggering the function, an attacker may execute arbitrary code in the context of the current process.
