A heap-based buffer overflow was discovered in the way RRSets are sorted before validating with DNSSEC data. An attacker on the network, who can forge DNS replies such as that they are accepted as valid, could use this flaw to cause a buffer overflow with arbitrary data in a heap memory segment, possibly executing code on the machine. The highest threat from this vulnerability is to data confidentiality and integrity as well as system availability.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "creation_timestamp": "2021-01-20T20:27:26.000000Z"}, {"uuid": "4ee99bf0-1287-4c54-95ae-b08155987cf8", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2020-25681", "type": "seen", "source": "https://t.me/CyberSecurityTechnologies/2534", "content": "#Whitepaper\n#Threat_Research\n\"DNSpooq: Cache Poisoning and RCE in Popular DNS Forwarder dnsmasq\", 2021.\n// CVE-2020-25684, CVE-2020-25685, \nCVE-2020-25686 - DNS-spoofing; CVE-2020-25681, CVE-2020-25682, CVE-2020-25683, CVE-2020-25687 - RCE.", "creation_timestamp": "2021-01-21T02:28:28.000000Z"}, {"uuid": "02c4f872-a216-46bf-80a6-1d29b42df8e5", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2020-25681", "type": "published-proof-of-concept", "source": "https://t.me/cissp/2224", "content": "#Whitepaper\n#Threat_Research\n\"DNSpooq: Cache Poisoning and RCE in Popular DNS Forwarder dnsmasq\", 2021.\n// CVE-2020-25684, CVE-2020-25685, \nCVE-2020-25686 - DNS-spoofing; CVE-2020-25681, CVE-2020-25682, CVE-2020-25683, CVE-2020-25687 - RCE.", "creation_timestamp": "2026-09-01T17:01:04.060874Z"}, {"uuid": "28e06cfb-cfda-473f-bb8c-4c153593bf43", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2020-25681", "type": "seen", "source": "https://t.me/hacking_Attack/6537", "content": "Cisco Security Advisory\nMultiple Vulnerabilities in dnsmasq DNS Forwarder Affecting Cisco Products: January 2021\n\nA set of previously unknown vulnerabilities in the DNS forwarder implementation of dnsmasq were disclosed on January 19, 2021.
