VAR-200611-0067
Vulnerability from variot - Updated: 2025-04-10 23:16The \Device\SandBox driver in Outpost Firewall PRO 4.0 (964.582.059) allows local users to cause a denial of service (system crash) via an invalid argument to the DeviceIoControl function that triggers an invalid memory operation. Outpost Firewall PRO is prone to a local denial-of-service vulnerability because the application fails to properly handle unexpected input. Exploiting this issue allows local attackers to crash affected computers, denying service to legitimate users. Outpost Firewall PRO 4.0 (964.582.059) is vulnerable to this issue; other versions may also be affected.
To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.
The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios.
This includes: * Reason for rating * Extended description * Extended solution * Exploit code or links to exploit code * Deep links
