CVE-2023-50387 8 Fedoraproject, Isc, Microsoft and 5 more 18 Fedora, Bind, Windows Server 2008 and 15 more 2024-11-21 7.5 High
Certain DNSSEC aspects of the DNS protocol (in RFC 4033, 4034, 4035, 6840, and related RFCs) allow remote attackers to cause a denial of service (CPU consumption) via one or more DNSSEC responses, aka the "KeyTrap" issue. One of the concerns is that, when there is a zone with many DNSKEY and RRSIG records, the protocol specification implies that an algorithm must evaluate all combinations of DNSKEY and RRSIG records.
CVE-2023-26437 1 Powerdns 1 Recursor 2024-11-21 3.4 Low
Denial of service vulnerability in PowerDNS Recursor allows authoritative servers to be marked unavailable.This issue affects Recursor: through 4.6.5, through 4.7.4 , through 4.8.3.
CVE-2023-22617 1 Powerdns 1 Recursor 2024-11-21 7.5 High
A remote attacker might be able to cause infinite recursion in PowerDNS Recursor 4.8.0 via a DNS query that retrieves DS records for a misconfigured domain, because QName minimization is used in QM fallback mode. This is fixed in 4.8.1.
CVE-2022-37428 2 Fedoraproject, Powerdns 2 Fedora, Recursor 2024-11-21 6.5 Medium
PowerDNS Recursor up to and including 4.5.9, 4.6.2 and 4.7.1, when protobuf logging is enabled, has Improper Cleanup upon a Thrown Exception, leading to a denial of service (daemon crash) via a DNS query that leads to an answer with specific properties.
CVE-2022-27227 2 Fedoraproject, Powerdns 3 Fedora, Authoritative Server, Recursor 2024-11-21 7.5 High
In PowerDNS Authoritative Server before 4.4.3, 4.5.x before 4.5.4, and 4.6.x before 4.6.1 and PowerDNS Recursor before 4.4.8, 4.5.x before 4.5.8, and 4.6.x before 4.6.1, insufficient validation of an IXFR end condition causes incomplete zone transfers to be handled as successful transfers.
CVE-2021-36754 1 Powerdns 1 Authoritative Server 2024-11-21 7.5 High
PowerDNS Authoritative Server 4.5.0 before 4.5.1 allows anybody to crash the process by sending a specific query (QTYPE 65535) that causes an out-of-bounds exception.
CVE-2020-25829 2 Opensuse, Powerdns 3 Backports Sle, Leap, Recursor 2024-11-21 7.5 High
An issue has been found in PowerDNS Recursor before 4.1.18, 4.2.x before 4.2.5, and 4.3.x before 4.3.5. A remote attacker can cause the cached records for a given name to be updated to the Bogus DNSSEC validation state, instead of their actual DNSSEC Secure state, via a DNS ANY query. This results in a denial of service for installation that always validate (dnssec=validate), and for clients requesting validation when on-demand validation is enabled (dnssec=process).
CVE-2020-24698 1 Powerdns 1 Authoritative 2024-11-21 9.8 Critical
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker might be able to cause a double-free, leading to a crash or possibly arbitrary code execution. by sending crafted queries with a GSS-TSIG signature.
CVE-2020-24697 1 Powerdns 1 Authoritative 2024-11-21 7.5 High
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker can cause a denial of service by sending crafted queries with a GSS-TSIG signature.
CVE-2020-24696 1 Powerdns 1 Authoritative 2024-11-21 8.1 High
An issue was discovered in PowerDNS Authoritative through 4.3.0 when --enable-experimental-gss-tsig is used. A remote, unauthenticated attacker can trigger a race condition leading to a crash, or possibly arbitrary code execution, by sending crafted queries with a GSS-TSIG signature.
CVE-2020-17482 1 Powerdns 1 Authoritative 2024-11-21 4.3 Medium
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.
CVE-2020-14196 1 Powerdns 1 Recursor 2024-11-21 5.3 Medium
In PowerDNS Recursor versions up to and including 4.3.1, 4.2.2 and 4.1.16, the ACL restricting access to the internal web server is not properly enforced.
CVE-2020-12244 4 Debian, Fedoraproject, Opensuse and 1 more 5 Debian Linux, Fedora, Backports Sle and 2 more 2024-11-21 7.5 High
An issue has been found in PowerDNS Recursor 4.1.0 through 4.3.0 where records in the answer section of a NXDOMAIN response lacking an SOA were not properly validated in SyncRes::processAnswer, allowing an attacker to bypass DNSSEC validation.
CVE-2020-10995 4 Debian, Fedoraproject, Opensuse and 1 more 5 Debian Linux, Fedora, Backports Sle and 2 more 2024-11-21 7.5 High
PowerDNS Recursor from 4.1.0 up to and including 4.3.0 does not sufficiently defend against amplification attacks. An issue in the DNS protocol has been found that allow malicious parties to use recursive DNS services to attack third party authoritative name servers. The attack uses a crafted reply by an authoritative name server to amplify the resulting traffic between the recursive and other authoritative name servers. Both types of service can suffer degraded performance as an effect. This is triggered by random subdomains in the NSDNAME in NS records. PowerDNS Recursor 4.1.16, 4.2.2 and 4.3.1 contain a mitigation to limit the impact of this DNS protocol issue.
CVE-2020-10030 1 Powerdns 1 Recursor 2024-11-21 8.8 High
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.) Under some conditions, this issue can lead to the writing of one '\0' byte out-of-bounds on the stack, causing a denial of service or possibly arbitrary code execution.
CVE-2019-3871 2 Fedoraproject, Powerdns 2 Fedora, Authoritative Server 2024-11-21 N/A
A vulnerability was found in PowerDNS Authoritative Server before 4.0.7 and before 4.1.7. An insufficient validation of data coming from the user when building a HTTP request from a DNS query in the HTTP Connector of the Remote backend, allowing a remote user to cause a denial of service by making the server connect to an invalid endpoint, or possibly information disclosure by making the server connect to an internal endpoint and somehow extracting meaningful information about the response
CVE-2019-3807 1 Powerdns 1 Recursor 2024-11-21 N/A
An issue has been found in PowerDNS Recursor versions 4.1.x before 4.1.9 where records in the answer section of responses received from authoritative servers with the AA flag not set were not properly validated, allowing an attacker to bypass DNSSEC validation.
CVE-2019-3806 1 Powerdns 1 Recursor 2024-11-21 8.1 High
An issue has been found in PowerDNS Recursor versions after 4.1.3 before 4.1.9 where Lua hooks are not properly applied to queries received over TCP in some specific combination of settings, possibly bypassing security policies enforced using Lua.
CVE-2019-10203 2 Linux, Powerdns 2 Linux Kernel, Authoritative Server 2024-11-21 4.3 Medium
PowerDNS Authoritative daemon , pdns versions 4.0.x before 4.0.9, 4.1.x before 4.1.11, exiting when encountering a serial between 2^31 and 2^32-1 while trying to notify a slave leads to DoS.
CVE-2019-10163 2 Opensuse, Powerdns 3 Backports, Leap, Authoritative 2024-11-21 4.3 Medium
A Vulnerability has been found in PowerDNS Authoritative Server before versions 4.1.9, 4.0.8 allowing a remote, authorized master server to cause a high CPU load or even prevent any further updates to any slave zone by sending a large number of NOTIFY messages. Note that only servers configured as slaves are affected by this issue.
