Deep Freeze 9.00.020.5760 is vulnerable to an out-of-bounds read vulnerability by triggering the 0x70014 IOCTL code of the FarDisk.sys driver.
The DfDiskLo.sys driver in Faronics Deep Freeze Standard and Enterprise 8.10 and earlier allows local administrators to cause a denial of service (crash) and execute arbitrary code via a crafted IOCTL request that writes to arbitrary memory locations, related to the IofCallDriver function.
