It creates a websocket server that expands the capabilities of the various web-interfaces provided by the GeoVision software and may be necessary for them to function properly.\n\nThe Websocket server can accept various commands coming from localhost. One of them, `connectionInfo` is meant to provide the necessary details to connect to a camera. The handler associated with this command that we call`handle_connection_info` contains multiple instances of string copy that can overflow. The function `handle_connect_info` copies attacker-controlled JSON strings into fixed-size buffers using manual byte-by-byte loops that do not enforce length limits.\n\n\n\n\n#### Buffer Overflow in ip field","published":"2026-07-02T04:17:15.380","modified":"2026-07-02T16:51:29.583","cvss":{"score":8.3,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://talosintelligence.com/vulnerability_reports/TALOS-2026-2375"},{"type":"WEB","url":"https://www.geovision.com.tw/cyber_security.php"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-07-02T16:51:29.583"}}
