An issue has been found in PowerDNS Recursor 4.1.0 up to and including 4.3.0. It allows an attacker (with enough privileges to change the system's hostname) to cause disclosure of uninitialized memory content via a stack-based out-of-bounds read. It only occurs on systems where gethostname() does not have '\0' termination of the returned string if the hostname is larger than the supplied buffer. (Linux systems are not affected because the buffer is always large enough. OpenBSD systems are not affected because the returned hostname always has '\0' termination.) • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00052.html https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-2020-03.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/NMP72NJGKBWR5WEBXAWX5KSLQUDFTG6S https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/PS4ZN5XGENYNFKX7QIIOUCQQHXE37GJF • CWE-125: Out-of-bounds Read •

A vulnerability has been found in PowerDNS Authoritative Server before versions 4.1.10, 4.0.8 allowing an authorized user to cause the server to exit by inserting a crafted record in a MASTER type zone under their control. The issue is due to the fact that the Authoritative Server will exit when it runs into a parsing error while looking up the NS/A/AAAA records it is about to use for an outgoing notify. Se ha detectado una vulnerabilidad en Authoritative Server de PowerDNS anterior a versiones 4.1.10, 4.0.8, permitiendo a un usuario autorizado causar que el servidor salga mediante la inserción de un registro diseñado en una zona tipo MASTER bajo su control.
