before 1.18.4 might access already-freed memory in error code\npaths when demuxing certain malformed Matroska files (SA-2021-0002).\n\nGStreamer before 1.18.4 might cause heap corruption when parsing certain\nmalformed Matroska files (SA-2021-0003).\n\nGStreamer before 1.18.4 might do an out-of-bounds read when handling\ncertain RealMedia files or streams (SA-2021-0004).\n\nGStreamer before 1.18.4 might cause stack corruptions with streams that\nhave more than 64 audio channels (SA-2021-0005).\n\nIt might be possible for a malicious third party to trigger a crash in\nthe application, but possibly also an arbitrary code execution with the\nprivileges of the target user.","dates":{"published":"2021-04-15T19:03:58.000Z","modified":"2026-04-16T04:25:18.632Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[],"affected":[{"vendor":"mageia","product":"gstreamer1.0-libav","name":"gstreamer1.0-libav","label":"gstreamer1.0-libav","ecosystem":"Mageia","cpePart":null,"purl":"pkg:rpm/mageia/gstreamer1.0-libav","purlType":"rpm","versions":[{"text":"<
