[CLSA-2026:1790803691] unbound: Fix of 2 CVEs
Type:
security
Severity:
Important
Release date:
2026-09-30 21:28:25 UTC
Description:
- CVE-2026-81634: check the remaining buffer space in rrset_canonical() and rrset_canonicalize_to_buffer() before writing the signature, owner name and RDATA, so an oversized RRset can no longer overflow the heap buffer during DNSSEC canonicalization; includes the upstream unit test - CVE-2026-80225: cap the pipelined queries drained from one TCP/DoT connection per event-loop turn (NUM_TCP_PER_SELECT) and defer the rest with a zero-delay timer, so one client can no longer starve other connections
