{"id":"CVE-2020-6072","details":"An exploitable code execution vulnerability exists in the label-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing compressed labels in mDNS messages, the rr_decode function's return value is not checked, leading to a double free that could be exploited to execute arbitrary code. An attacker can send an mDNS message to trigger this vulnerability.","modified":"2026-07-07T08:50:46.816132484Z","published":"2020-03-24T21:15:14.143Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"introduced":"9.0"},{"last_affected":"9.0"}],"source":"CPE_STRING","vendor_product":"debian:debian_linux","cpes":["cpe:2.3:o:debian:debian_linux:9.0:*:*:*:*:*:*:*"]}]},"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-2020-0995"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/videolabs/libmicrodns","events":[{"introduced":"a12486a5aea85e0f3f02a3721855963b5f1e185f"},{"last_affected":"a12486a5aea85e0f3f02a3721855963b5f1e185f"}],"database_specific":{"cpe":"cpe:2.3:a:videolabs:libmicrodns:0.1.0:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0.1.0"},{"last_affected":"0.1.0"}],"source":"CPE_STRING"}}],"versions":["0.1.0"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2020-6072.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:H/I:H/A:H"}]}
