Fortinet FortiOS Contains a buffer error vulnerability.Service operation interruption (DoS) There is a possibility of being put into a state. Fortinet FortiOS is prone to a heap-based buffer-overflow vulnerability. \nAttackers can exploit this issue to cause denial-of-service conditions. \nVersions prior to FortiOS 6.0.5 are vulnerable. 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. A heap buffer overflow vulnerability existed in Fortinet versions prior to FortiOS 6.2.0. This vulnerability stems from the incorrect verification of data boundaries when the network system or product performs operations on the memory, resulting in incorrect read and write operations to other associated memory locations",
