Improper Restriction of Operations within the Bounds of a Memory Buffer
Buffer overflow in the H.323 filter of Microsoft Internet Security and Acceleration Server 2000 allows remote attackers to execute arbitrary code in the Microsoft Firewall Service via certain H.323 traffic, as demonstrated by the NISCC/OUSPG PROTOS test suite for the H.225 protocol.
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.
