Vulnerability Name:

CCN-131814

Published:2017-09-11
Updated:2017-09-11
Summary:NetBSD is vulnerable to a buffer overflow, caused by improper bounds checking by the graphics drivers. By sending a specially-crafted data, a local attacker could overflow a buffer and execute arbitrary code with kernel-level privileges on the system.
