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.","state":0,"publishedAt":"2020-03-24T20:39:31+00:00","modifiedAt":"2026-10-08T21:13:51.025+00:00","affected":[{"ecosystem":"Vendor product","name":"Videolabs","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Videolabs\",\n                    \"vendor\": \"n/a\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"Videolabs libmicrodns 0.1.0\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5,"severity":"HIGH"}],"references":["https://www.debian.org/security/2020/dsa-4671","https://security.gentoo.org/glsa/202005-10","https://talosintelligence.com/vulnerability_reports/TALOS-2020-1001"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2020-6078","license":"CVE Program Terms of Use","key":"cve-program:CVE-2020-6078","identifiers":["CVE-2020-6078"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
