{"id":"ALPINE-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":"2026-11-03T06:32:37.517326670Z","published":"2020-03-24T21:15:14.363Z","upstream":["CVE-2020-6078"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2020-6078"}],"affected":[{"package":{"name":"vlc","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}},{"package":{"name":"vlc","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/vlc?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.0.9.2-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2020-6078.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
