Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity High
Score 7.5/10


Stack-based buffer overflow in the LZC decompression implementation (CsObjectInt::CsDecomprLZC function in vpa106cslzc.cpp) in SAP MaxDB 7.5 and 7.6, Netweaver Application Server ABAP, Netweaver Application Server Java, Netweaver RFC SDK, GUI, RFC SDK, SAPCAR archive tool, and other products allows context-dependent attackers to cause a denial of service (crash) or possibly execute arbitrary code via unspecified vectors, aka SAP Security Note 2124806, 2121661, 2127995, and 2125316.

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.
