Hello, Сommunity!

The VyOS 1.4.0-epa3 (Early Production Access) release is now available to subscribers. It includes a fix for CVE-2024-2961 — the recently discovered buffer overflow vulnerability in GNU libc.

This is the final EPA of 1.4.0/Sagitta release, which includes all supported flavors (hardware and virtual). It also includes a few configuration syntax changes (all automatically migrated) that were required to make old configs work or to unblock improvement paths, such as implementing the DHCP server active/active high availability mode in addition to the old active/passive failover mechanism.

Please let us know if you notice any anomalies! We expect the 1.4.0 GA release in two weeks if no significant issues are detected.
