Vulnerability from variot

An integer overflow or wraparound vulnerability in the memory allocator of SSLVPN in FortiOS before 7.0.1 may allow an unauthenticated attacker to corrupt control data on the heap via specifically crafted requests to SSLVPN, resulting in potentially arbitrary code execution. FortiOS Exists in an integer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. Fortinet FortiOS is a set of security operating system dedicated to the FortiGate network security platform developed by Fortinet. The system provides users with various security functions such as firewall, anti-virus, IPSec/SSLVPN, Web content filtering and anti-spam
