{"id":"CVE-2020-6079","details":"An exploitable denial-of-service vulnerability exists in the resource allocation handling of Videolabs libmicrodns 0.1.0. When encountering errors while parsing mDNS messages, some allocated data is not freed, possibly leading to a denial-of-service condition via resource exhaustion. An attacker can send one mDNS message repeatedly to trigger this vulnerability through decoding of the domain name performed by rr_decode.","modified":"2026-05-18T05:52:37.020472453Z","published":"2020-03-24T21:15:14.427Z","database_specific":{"unresolved_ranges":[{"cpes":["cpe:2.3:o:debian:debian_linux:10.0:*:*:*:*:*:*:*","cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"],"source":"CPE_FIELD","vendor_product":"debian:debian_linux","extracted_events":[{"last_affected":"9.0"},{"last_affected":"10.0"}]}]},"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-2020-1002"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/videolabs/libmicrodns","events":[{"introduced":"0"},{"last_affected":"a12486a5aea85e0f3f02a3721855963b5f1e185f"}],"database_specific":{"cpe":"cpe:2.3:a:videolabs:libmicrodns:0.1.0:*:*:*:*:*:*:*","source":"CPE_FIELD","extracted_events":[{"introduced":"0"},{"last_affected":"0.1.0"}]}}],"versions":["0.1.0","0.0.10","0.0.9","0.0.8","0.0.7","0.0.6","0.0.5","0.0.4","0.0.3","0.0.2","0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-6079.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
