{"id":"UBUNTU-CVE-2020-6071","details":"An exploitable denial-of-service vulnerability exists in the resource record-parsing functionality of Videolabs libmicrodns 0.1.0. When parsing compressed labels in mDNS messages, the compression pointer is followed without checking for recursion, leading to a denial of service. An attacker can send an mDNS message to trigger this vulnerability.","modified":"2026-02-04T04:13:25.395157Z","published":"2020-03-24T21:15:00Z","related":["USN-7239-1"],"upstream":["CVE-2020-6071"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2020-6071"},{"type":"REPORT","url":"https://talosintelligence.com/vulnerability_reports/TALOS-2020-0994"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2020-6071"},{"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":{"binaries":[{"binary_name":"libmicrodns-dev","binary_version":"0.0.8-1ubuntu0.1~esm1"},{"binary_name":"libmicrodns0","binary_version":"0.0.8-1ubuntu0.1~esm1"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-6071.json"}},{"package":{"name":"vlc","ecosystem":"Ubuntu:Pro:18.04:LTS","purl":"pkg:deb/ubuntu/vlc@3.0.8-0ubuntu18.04.1+esm3?arch=source&distro=esm-apps/bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.8-0ubuntu18.04.1+esm3"}]}],"versions":["2.2.6-6","2.2.6-6build1","2.2.7-1","2.2.8-1","2.2.8-1ubuntu4","2.2.8-2","3.0.0~rc1-1ubuntu1","3.0.0~rc1-1ubuntu3","3.0.0~rc2-1ubuntu1","3.0.0~rc2-2ubuntu1","3.0.0~rc2-2ubuntu2","3.0.0~rc4-1ubuntu1","3.0.0~rc7-2ubuntu1","3.0.0~rc8-1ubuntu1","3.0.0-1ubuntu1","3.0.1-1ubuntu5","3.0.1-2ubuntu1","3.0.1-2ubuntu2","3.0.1-3","3.0.1-3build1","3.0.2-0ubuntu0.1","3.0.3-1-1ubuntu1","3.0.4-1ubuntu0.2","3.0.7.1-0ubuntu18.04.1","3.0.8-0ubuntu18.04.1","3.0.8-0ubuntu18.04.1+esm1","3.0.8-0ubuntu18.04.1+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"libvlc-bin","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"libvlc-dev","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"libvlc5","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"libvlccore-dev","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"libvlccore9","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-bin","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-data","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-l10n","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-access-extra","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-base","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-fluidsynth","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-jack","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-notify","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-qt","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-samba","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-skins2","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-svg","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-video-output","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-video-splitter","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-visualization","binary_version":"3.0.8-0ubuntu18.04.1+esm3"},{"binary_name":"vlc-plugin-zvbi","binary_version":"3.0.8-0ubuntu18.04.1+esm3"}],"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro"},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2020/UBUNTU-CVE-2020-6071.json"}}],"schema_version":"1.7.3","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"}]}
