Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity Medium
Score 4/10


Multiple buffer overflows in the JAR file administration routines in the BSU JAVA subcomponent in IBM DB2 8 before FP16, 9.1 before FP4a, and 9.5 before FP1 allow remote authenticated users to cause a denial of service (instance crash) via a call to the (1) RECOVERJAR or (2) REMOVE_JAR procedure with a crafted parameter, related to (a) sqlj.install_jar and (b) sqlj.replace_jar.

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.
