-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3139-1 debian-...@lists.debian.org https://www.debian.org/lts/security/ Chris Lamb October 07, 2022 https://wiki.debian.org/LTS - -------------------------------------------------------------------------
Package : knot-resolver Version : 3.2.1-3+deb10u1 CVE ID : CVE-2022-40188 It was discovered that there was a potential remote denial-of-service vulnerability in the knot-resolver DNSSEC-validating DNS resolver. Remote attackers could have caused a denial of service via CPU consumption by exploiting algorithmic complexity: during an attack, an authoritative server would return large nameserver or address sets. For Debian 10 buster, this problem has been fixed in version 3.2.1-3+deb10u1. We recommend that you upgrade your knot-resolver packages. For the detailed security status of knot-resolver please refer to its security tracker page at: https://security-tracker.debian.org/tracker/knot-resolver Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: https://wiki.debian.org/LTS -----BEGIN PGP SIGNATURE----- iQIzBAEBCAAdFiEEwv5L0nHBObhsUz5GHpU+J9QxHlgFAmNAevAACgkQHpU+J9Qx HlgkFA//R2BL637krNYF/D2TPAMPsoB/9ym+oDwWDJfsXhcaocMhoy4p+OU8D11O WB5K3FLSoeiYK/0BLHdghZsVEgdOhIuNJ/8DLXbRBlCdA/tWO+e9b8sagehfHMx4 FuXM3yheAr7eqYjMVLJGczFvt+HkWRzKMcNYGEjHdrYAn2izdbvWt4uFicqpIJ+c 4ZKTT7pNau/a3E8VwzlLcwsN+P8+mC/TlhEqV2TOviqtfDiGLC94Zj5GHGiHc5I2 xP2PmAwLOZwrAK26qXXX6uya8jiKpwfdjSLnPGDXIRaqMwRyFDQQ7LYhaCrtAjHb 3foy5KOX6tw0ZVncZFELRXulS4HLzRU1rfH2HxsDnSbirpHsl6asJ3BuHlRYizOI gr6nEzaEXSm/L8l5qV2JtPPLddkx6lQzJBEjM9Y4piKuCJYeTdvxmFIjB1WC21Jl cj2o9mmL6Dx/8iLtI4hH/U8+uxw9pNGCZe0/2Vmzlhs3I8RtKPX46uNTuXHPtovB OUvdlVBrpoHSVHpzPpWuBf69XsL4F2EYnV6KM+XJ725fwHHGLpe0cm7DKQT+a32L 0TezuEM23R9+Lyb6d+ladcFvLOGmsZ7zmjfcqecSOQHv7nFG6+vWxTXIxVdOkcnr jjocxfOT/WKwNqARjmn+13dBlu5uGT/kFBpv8qPtcejrEAiD/SU= =seYr -----END PGP SIGNATURE-----
