Name of the Vulnerable Software and Affected Versions
tinytag versions 2.2.0
Description
tinytag version 2.2.0 contains an issue where an attacker who can supply MP3 files for parsing can trigger a non-terminating loop while the library parses an ID3v2 SYLT (synchronized lyrics) frame. In server-side deployments that automatically parse attacker-supplied files, a single 498-byte MP3 can cause the parsing operation to stop making progress and remain busy until the worker or process is terminated. The root cause is that
parse synced lyrics assumes find string end pos always returns a position greater than the current offset, which is false when no string terminator is present in the remaining frame content. The vulnerable call path involves TinyTag.get, load, parse tag, parse id3v2, parse frame, parse synced lyrics, and find string end pos. The SYLT parsing support was introduced in version 2.2.0.Recommendations
Update to version 2.2.1 or later to resolve this issue.
