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:
https://security-tracker.debian.org/tracker/unbound
