Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 10/10


Multiple stack-based buffer overflows in the HanGamePluginCn18.HanGamePluginCn18.1 ActiveX control in HanGamePluginCn18.dll in Ourgame GLWorld (aka Lianzong Game Platform) allow remote attackers to execute arbitrary code via long arguments to the (1) hgs_startGame and (2) hgs_startNotify methods, as exploited in the wild as of February 2008. NOTE: some of these details are obtained from third party information.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
