Debian Security Advisory DSA-4544-1 [email protected]
https://www.debian.org/security/ Sebastien Delafond
October 16, 2019 https://www.debian.org/security/faq
Package : unbound
CVE ID : CVE-2019-16866
Debian Bug : 941692
X41 D-Sec discovered that unbound, a validating, recursive, and
caching DNS resolver, did not correctly process some NOTIFY
queries. This could lead to remote denial-of-service by application
crash.
For the stable distribution (buster), this problem has been fixed in
version 1.9.0-2+deb10u1.
We recommend that you upgrade your unbound packages.
For the detailed security status of unbound please refer to
its security tracker page at:
