Improper Restriction of Operations within the Bounds of a Memory Buffer
Buffer overflow in Unreal Tournament 3 1.3beta4 and earlier allows remote attackers to cause a denial of service (memory corruption and daemon crash) or possibly execute arbitrary code via a UDP packet containing a large value in a certain size field, followed by a data string of that size, aka attack 1 in ut3mendo.c.
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.
