    Package        : unbound
    CVE ID         : CVE-2020-12662 CVE-2020-12663
    
    Two vulnerabiliites have been discovered in Unbound, a recursive-only
    caching DNS server; a traffic amplification attack against third party
    authoritative name servers (NXNSAttack) and insufficient sanitisation
    of replies from upstream servers could result in denial of service via
    an infinite loop.
    
    The version of Unbound in the oldstable distribution (stretch) is
    no longer supported. If these security issues affect your setup, you
    should upgrade to the stable distribution (buster).
    
    For the stable distribution (buster), these problems have been fixed in
    version 1.9.0-2+deb10u2.
    
    We recommend that you upgrade your unbound packages.
    
    For the detailed security status of unbound please refer to
    its security tracker page at:
