Multiple G DATA products GDTdiIcpt.sys privilege escalation

gdata-gdtdiicpt-privilege-escalation (45249) The risk level is classified as HighHigh Risk

Description:

Multiple G DATA products could allow a local attacker to gain elevated privileges on the system, caused by improper validation of requests by the GDTdiIcpt.sys kernel driver. By sending a specially-crafted IOCTL request, a local attacker could exploit this vulnerability to corrupt memory and execute arbitrary code on the system with kernel level privileges or cause a kernel panic.
