Multiple Symantec Antivirus IOCTL device driver privilege escalation
| symantec-ioctl-privilege-escalation (29360) |  High Risk |
Description:
Multiple Symantec Antivirus products could allow a local attacker to gain elevated privileges on the system, caused by a vulnerability in the NAVEX15.SYS and NAVENG.SYS device drivers. By sending a specially-crafted Irp to the IOCTL function, a local attacker could overwrite supplied addresses and execute arbitrary code on the system with kernel level privileges.
