High
7.5/10

Summary

Microsoft Internet Explorer 5.01 and 6 does not properly handle uninitialized COM objects, which allows remote attackers to cause a denial of service (memory corruption) and possibly execute arbitrary code, as demonstrated by the Nth function in the DirectAnimation.DATuple ActiveX control, aka "COM Object Instantiation Memory Corruption Vulnerability."

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.
