Release date: 20 July, 2026
Version: 2.0.382
FastNetMon Advanced 2.0.382 is a security-focused maintenance release that strengthens the platform's resilience against malformed network telemetry and configuration validation issues. This release addresses multiple security advisories by improving the robustness of sFlow, NetFlow v9/IPFIX, and packet parsing, eliminating a potential race condition in template handling, and adding strict validation for supported email authentication methods.
Changes:
- Added sanity check to ensure that malicious actor cannot manipulate length of sFlow sample. Addresses: GHSA-852r-3wcv-pjx2
- Added limit for length of Netflow v9 interface name to address security issue GHSA-ff5f-p5jw-8fq2
- Implemented logic to make full copy of Netflow / IFIX template to avoid potential race condition during template update, addresses GHSA-ph88-95vc-x6gv
- Addressed security vulnerability in packet parser when IPv6 fragments are involved: GHSA-jmjw-392h-4g93
- Added validation for email_notifications_auth_method to allow only following options: scram-sha-256-plus, scram-sha-1-plus, scram-sha-256, scram-sha-1, plain, gssapi, external, oauthbearer, cram-md5, digest-md5, login, ntlm, xoauth2
