Improper Restriction of Operations within the Bounds of a Memory Buffer
An issue was discovered in EMC Data Domain DD OS 5.7 family, versions prior to 126.96.36.199; EMC Data Domain DD OS 6.0 family, versions prior to 188.8.131.52; EMC Data Domain DD OS 6.1 family, versions prior to 184.108.40.206; EMC Data Domain Virtual Edition 2.0 family, all versions; EMC Data Domain Virtual Edition 3.0 family, versions prior to 3.0 SP2 Update 1; and EMC Data Domain Virtual Edition 3.1 family, versions prior to 3.1 Update 2. EMC Data Domain DD OS contains a memory overflow vulnerability in SMBv1 which may potentially be exploited by an unauthenticated remote attacker. An attacker may completely shut down both the SMB service and active directory authentication. This may also allow remote code injection and execution.
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.
