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.
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.
