Loss of Integrity
Exploit Public

- 漏洞描述

An overflow exists in Gnocatan. Gnocatan fails to check boundary, resulting in a buffer overflow. With a specially crafted request, an attacker could overflow a buffer and execute arbitrary code on the system or cause a denial of service, resulting in a loss of integrity.
