{"id":"UBUNTU-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":"2026-04-22T12:42:02.031787Z","published":"2020-03-24T21:15:00Z","related":["USN-7239-1"],"upstream":["CVE-2020-6077"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-6077"},{"type":"REPORT","url":"https://talosintelligence.com/vulnerability_reports/TALOS-2020-1000"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-6077"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7239-1"}],"affected":[{"package":{"name":"libmicrodns","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/libmicrodns@0.0.8-1ubuntu0.1~esm1?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.0.8-1ubuntu0.1~esm1"}]}],"versions":["0.0.7-2","0.0.8-1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"libmicrodns0","binary_version":"0.0.8-1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-6077.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"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
