About NSD
Memory work paid off, then a serious SVCB overflow arrived — and Prometheus users get a breaking relabel.
NSD's recent history runs through three arcs. The 4.14.0 release refactored RDATA storage to cut memory footprint, a regression was reported immediately for zones with large RRsets, and 4.14.1 closed that gap so consumption dropped in all cases. In June, 4.14.3 fixed two CVEs, one a heap overflow of up to 65,509 attacker-controlled bytes reachable through a crafted SVCB record. Then 4.15.0 moved zone identity in Prometheus metrics from the metric name into a label, with an explicit warning that current users must adapt. Every release ships as an rc1 with identical notes before the final.
