Open-Xchange: Recursor accepts unsigned, empty NXDOMAINs in secure zones

Hi! This is a slightly edited version of the email I sent to the project's security contacts on 2020-04-21.

Authorization Bypass

bind is vulnerable to authorization bypass. The vulnerability exists as it was discovered that, in certain cases, named did not properly perform DNSSEC validation of an NS RRset for zones in the middle of a DNSKEY algorithm rollover. This flaw could cause the validator to incorrectly determine th...

Denial Of Service (DoS)

bind is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the DNSSEC validation code in named. If named had multiple trust anchors configured for a zone, a response to a request for a record in that zone with a bad signature could cause named to crash...

Cache Poisoning Attack

bind is vulnerable to cache poisoning attacks. The vulnerability exists as a flaw was found in the BIND DNSSEC NSEC/NSEC3 validation code. If BIND was running as a DNSSEC-validating resolver, it could incorrectly cache NXDOMAIN responses, as if they were valid, for records proven by NSEC or NSEC3...

Cache Poisoning Attack

bind is vulnerable to cache poisoning attack. The vulnerability exists as BIND was incorrectly caching responses without performing proper DNSSEC validation, when those responses were received during the resolution of a recursive client query that requested DNSSEC records but indicated that...

DSA Certificate Validation Bypass

bind is vulnerable to DSA certificate validation bypass. The vulnerability exists as a flaw was discovered in the way BIND checked the return value of the OpenSSL DSAdoverify function. On systems using DNSSEC, a malicious zone could present a malformed DSA certificate and bypass proper certificat...

Denial Of Service (DoS)

bind is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the way BIND processed certain DNS query responses. On servers that had enabled DNSSEC validation, this could allow a remote attacker to cause a denial of service...
