Improper Restriction of Operations within the Bounds of a Memory Buffer
LGSERVER.EXE in BrightStor ARCserve Backup for Laptops & Desktops r11.1 allows remote attackers to cause a denial of service (daemon crash) via a value of 0xFFFFFFFF at a certain point in an authentication negotiation packet, which results in an out-of-bounds read.
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.
