{"id":"CVE-2020-6077","details":"An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages, the implementation does not properly keep track of the available data in the message, possibly leading to an out-of-bounds read that would result in a denial of service. An attacker can send an mDNS message to trigger this vulnerability.","modified":"2026-07-07T08:50:46.815897889Z","published":"2020-03-24T21:15:14.300Z","database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"}],"source":"CPE_STRING","vendor_product":"debian:debian_linux"}]},"references":[{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202005-10"},{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4671"},{"type":"EVIDENCE","url":"https://talosintelligence.com/vulnerability_reports/TALOS-2020-1000"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/videolabs/libmicrodns","events":[{"introduced":"a12486a5aea85e0f3f02a3721855963b5f1e185f"},{"last_affected":"a12486a5aea85e0f3f02a3721855963b5f1e185f"}],"database_specific":{"source":"CPE_STRING","cpe":"cpe:2.3:a:videolabs:libmicrodns:0.1.0:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.1.0"},{"last_affected":"0.1.0"}]}}],"versions":["0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-6077.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
