Detail

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