Summary

Buffer overflow in the ftp client in IBM AIX 5.3 SP6 and 5.2.0 allows local users to execute arbitrary code via unspecified vectors that trigger the overflow in a gets function call. NOTE: the client is setuid root on AIX, so this issue crosses privilege boundaries.

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.
