Agnitum Outpost Firewall 4.0

Agnitum Outpost Firewall PRO 4.0 allows local users to bypass access restrictions and insert Trojan horse drivers into the product's installation directory by creating links using FileLinkInformation requests with the ZwSetInformationFile function, as demonstrated by modifying SandBox.sys.

The \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.

Unrestricted critical resource lock in Agnitum Outpost Firewall PRO 4.0 1007.591.145 and earlier allows local users to cause a denial of service (system hang) by capturing the outpost_ipc_hdr mutex.
