music-metadata: EBML parser trusts element lengths, allowing memory exhaustion or process abort

Summary The Matroska/WebM EBML parser decodes attacker-controlled variable-length integer VINT element lengths without first validating that the declared element fits within its enclosing container or the available input. Leaf lengths are then used directly for string-token and Uint8Array...
