Summary
Fix CVE(s): CVE-2026-6949
Details
  • SECURITY UPDATE: out-of-bounds write in the internal DNS server via a TSIG-signed packet using DNS name compression
    • debian/patches/CVE-2026-6949.patch: record the start offset of each dns_res_rec while pulling it and use the last additional record's offset to truncate the buffer for TSIG verification, instead of subtracting a re-pushed TSIG record length that can exceed the packet and underflow packet_len into a huge memcpy() size
