Description Guilherme de Almeida Suckevicz 2020-09-22 20:53:06 UTC

An issue has been found in PowerDNS Authoritative Server before 4.3.1 where an authorized user with the ability to insert crafted records into a zone might be able to leak the content of uninitialized memory. Such a user could be a customer inserting data via a control panel, or somebody with access to the REST API. Crafted records cannot be inserted via AXFR.
