Name of the Vulnerable Software and Affected Versions Sandboxie versions prior to 1.17.3

Description A local denial of service exists in the Sandboxie kernel driver. An unprivileged process running inside a Standard Sandbox can send a malformed IOCTL (Input/Output Control) to the 'DeviceSandboxieDriverApi' driver, triggering an immediate kernel crash resulting in a Blue Screen of Death (BSOD). This issue affects the Standard Sandbox configuration regardless of whether administrator privileges are dropped, but it does not affect the Security Hardened Sandbox configuration.

Recommendations Update to version 1.17.3. As a temporary workaround, use the Security Hardened Sandbox configuration.
