HighCVSS 7.5 EPSS 1.1%
MaraDNS is open-source software that implements the Domain Name System (DNS). In version 3.5.0024 and prior, a remotely exploitable integer underflow vulnerability in the DNS packet decompression function allows an attacker to cause a Denial of Service by triggering an abnormal p...

HighCVSS 7.5 EPSS 0.97%
An issue was discovered in MaraDNS Deadwood through 3.5.0021 that allows variant V1 of unintended domain name resolution. A revoked domain name can still be resolvable for a long time, including expired domains and taken-down malicious domains. The effects of an exploit would be...

The resolver in MaraDNS before 1.3.0.7.15 and 1.4.x before 1.4.12 overwrites cached server names and TTL values in NS records during the processing of a response to an A record query, which allows remote attackers to trigger continued resolvability of revoked domain names via a "...

HighCVSS 7.8 EPSS 2.7%
MaraDNS before 1.3.07.12 and 1.4.x before 1.4.08 computes hash values for DNS data without restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted queries with the Recursi...

MaraDNS 1.3.07.12 and 1.4.08 computes hash values for DNS data without properly restricting the ability to trigger hash collisions predictably, which allows remote attackers to cause a denial of service (CPU consumption) by sending many crafted queries with the Recursion Desired...

HighCVSS 7.5 EPSS 5.2%
The compress_add_dlabel_points function in dns/Compress.c in MaraDNS 1.4.03, 1.4.05, and probably other versions allows remote attackers to cause a denial of service (segmentation fault) and possibly execute arbitrary code via a long DNS hostname with a large number of labels, wh...

MediumCVSS 4.3 EPSS 1.9%
parse/Csv2_parse.c in MaraDNS 1.3.03, and other versions before 1.4.03, does not properly handle hostnames that do not end in a "." (dot) character, which allows remote attackers to cause a denial of service (NULL pointer dereference) via a crafted csv2 zone file.

MediumCVSS 5.0 EPSS 2.1%
MaraDNS 1.0 before 1.0.41, 1.2 before 1.2.12.08, and 1.3 before 1.3.07.04 allows remote attackers to cause a denial of service via a crafted DNS packet that prevents an authoritative name (CNAME) record from resolving, aka "improper rotation of resource records."

MediumCVSS 5.0 EPSS 1.4%
Memory leak in server/MaraDNS.c in MaraDNS 1.2.12.06 and 1.3.05 allows remote attackers to cause a denial of service (memory consumption) via unspecified vectors, a different set of affected versions than CVE-2007-3114 and CVE-2007-3115.

HighCVSS 7.8 EPSS 2.4%
Multiple memory leaks in server/MaraDNS.c in MaraDNS before 1.2.12.06, and 1.3.x before 1.3.05, allow remote attackers to cause a denial of service (memory consumption) via (1) reverse lookups or (2) requests for records in a class other than Internet (IN), a different set of aff...
