Summary
Fix CVE(s): CVE-2023-32067
Details
  • SECURITY UPDATE: denial of service via a 0-length UDP packet
    • debian/patches/CVE-2023-32067.patch: in read_udp_packets() in ares_process.c, treat a 0-length UDP read as a 0-length packet and keep reading instead of tearing the server connection down; only a negative return value is now an error, and an answer from a mismatched address no longer stops the read loop.
    • CVE-2023-32067
