Overview
Affected versions of this package are vulnerable to Out-of-bounds Write in the resolve_content_path process. An attacker can cause a write operation to occur one byte past the end of a heap-allocated buffer by crafting a specially designed MPEG-DASH manifest that triggers the appending of a / character to a buffer that is not large enough to accommodate it, leading to memory corruption.
