Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 10/10


Heap-based buffer overflow in the Data Protection for SQL CAD service (aka dsmcat.exe) in the Client Acceptor Daemon (CAD) and the scheduler in the Backup-Archive client through, through, through, through, and through in IBM Tivoli Storage Manager (TSM); and the Backup-Archive client in TSM Express; allows remote attackers to execute arbitrary code by sending a large amount of crafted data to a TCP port.

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.
