CWE-120

4,412 CVEs • Abstraction: Base • Likelihood of Exploit: High

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.

An exploitable buffer overflow exists in the Joyent SmartOS 20161110T013148Z Hyprlofs file system. The vulnerability is present in the Ioctl system call with the command HYPRLOFS_ADD_ENTRIES when dealing with 32-bit file systems. An attacker can craft an input that can cause a buffer overflow in the nm variable leading to an out of bounds memory access and could result in potential privilege escalation. This vulnerability is distinct from CVE-2016-9032.Show less
