Vulnerability from variot - Updated: 2023-12-18 12:17

A stack buffer overflow vulnerability in FortiClient for Linux 6.2.1 and below may allow a user with low privilege to cause FortiClient processes running under root priviledge crashes via sending specially crafted "StartAvCustomScan" type IPC client requests to the fctsched process due the argv data not been well sanitized. Linux for FortiClient Is vulnerable to out-of-bounds writes.Service operation interruption (DoS) It may be put into a state. Fortinet FortiClient is a mobile terminal security solution developed by Fortinet. The solution provides IPsec and SSL encryption, WAN optimization, endpoint compliance, and two-factor authentication when connected to FortiGate firewall appliances. A buffer error vulnerability exists in Fortinet FortiClient 6.2.1 and earlier versions based on the Linux platform. Attackers can use this vulnerability to cause denial of service through IPC sockets
