CVE-2018-14644 (GCVE-0-2018-14644)
Vulnerability from nvd – Published: 2018-11-09 19:00 – Updated: 2024-08-05 09:38
VLAI
Summary
An issue has been found in PowerDNS Recursor from 4.0.0 up to and including 4.1.4. A remote attacker sending a DNS query for a meta-type like OPT can lead to a zone being wrongly cached as failing DNSSEC validation. It only arises if the parent zone is signed, and all the authoritative servers for that parent zone answer with FORMERR to a query for at least one of the meta-types. As a result, subsequent queries from clients requesting DNSSEC validation will be answered with a ServFail.

CVE-2016-2120 (GCVE-0-2016-2120)
Vulnerability from nvd – Published: 2018-11-01 13:00 – Updated: 2024-08-05 23:17
VLAI
Summary
An issue has been found in PowerDNS Authoritative Server versions up to and including 3.4.10, 4.0.1 allowing an authorized user to crash the server by inserting a specially crafted record in a zone under their control then sending a DNS query for that record. The issue is due to an integer overflow when checking if the content of the record matches the expected size, allowing an attacker to cause a read past the buffer boundary.

CVE-2018-1046 (GCVE-0-2018-1046)
Vulnerability from nvd – Published: 2018-07-16 20:00 – Updated: 2024-08-05 03:44
VLAI
Summary
pdns before version 4.1.2 is vulnerable to a buffer overflow in dnsreplay. In the dnsreplay tool provided with PowerDNS Authoritative, replaying a specially crafted PCAP file can trigger a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution. This buffer overflow only occurs when the -ecs-stamp option of dnsreplay is used.

CVE-2016-2120 (GCVE-0-2016-2120)
Vulnerability from cvelistv5 – Published: 2018-11-01 13:00 – Updated: 2024-08-05 23:17
VLAI
Summary
An issue has been found in PowerDNS Authoritative Server versions up to and including 3.4.10, 4.0.1 allowing an authorized user to crash the server by inserting a specially crafted record in a zone under their control then sending a DNS query for that record. The issue is due to an integer overflow when checking if the content of the record matches the expected size, allowing an attacker to cause a read past the buffer boundary.

CVE-2018-1046 (GCVE-0-2018-1046)
Vulnerability from cvelistv5 – Published: 2018-07-16 20:00 – Updated: 2024-08-05 03:44
VLAI
Summary
pdns before version 4.1.2 is vulnerable to a buffer overflow in dnsreplay. In the dnsreplay tool provided with PowerDNS Authoritative, replaying a specially crafted PCAP file can trigger a stack-based buffer overflow, leading to a crash and potentially arbitrary code execution. This buffer overflow only occurs when the -ecs-stamp option of dnsreplay is used.
