{"id":"CVE-2020-6078","details":"An exploitable denial-of-service vulnerability exists in the message-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing mDNS messages in mdns_recv, the return value of the mdns_read_header function is not checked, leading to an uninitialized variable usage that eventually results in a null pointer dereference, leading to service crash. An attacker can send a series of mDNS messages to trigger this vulnerability.","modified":"2026-04-16T04:43:36.166776320Z","published":"2020-03-24T21:15:14.363Z","references":[{"type":"ADVISORY","url":"https://www.debian.org/security/2020/dsa-4671"},{"type":"ADVISORY","url":"https://security.gentoo.org/glsa/202005-10"},{"type":"EVIDENCE","url":"https://talosintelligence.com/vulnerability_reports/TALOS-2020-1001"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/videolabs/libmicrodns","events":[{"introduced":"0"},{"last_affected":"a12486a5aea85e0f3f02a3721855963b5f1e185f"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"0.1.0"}]}}],"versions":["0.0.1","0.0.10","0.0.2","0.0.3","0.0.4","0.0.5","0.0.6","0.0.7","0.0.8","0.0.9","0.1.0"],"database_specific":{"unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"9.0"}]},{"events":[{"introduced":"0"},{"last_affected":"10.0"}]}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-6078.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"}]}
