Improper Restriction of Operations within the Bounds of a Memory Buffer


Severity Medium
Score 5/10


Dibbler 0.6.0 does not verify that certain length parameters are appropriate for buffer sizes, which allows remote attackers to trigger a buffer over-read and cause a denial of service (daemon crash), as demonstrated by incorrect behavior of the TSrvMsg constructor in SrvMessages/SrvMsg.cpp when (1) reading the option code and option length and (2) parsing options.

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.
