Updated libebml packages fix security vulnerabilities: Heap use-after-free when parsing malformed file. A flaw was found in libebml before 1.4.2. A heap overflow bug exists in the implementation of EbmlString::ReadData and EbmlUnicodeString::ReadData in libebml (CVE-2021-3405). The mkvtoolnix, libmatroska packages have been rebuilt for the updated libebml.
