A GitHub-reviewed security advisory, not necessarily under active exploitation the way our CISA KEV advisories are, but a real, disclosed vulnerability in an open-source dependency.
Affected packages
Vulnerable: >= 2.0.0, < 2.3.0
Patched in 2.3.0
Details
An M4A file containing a sub-atom with a size of zero in the ---- atom makes the parser enter an infinite loop, resulting in a denial-of-service for programs reading such files with tinytag.
The issue has been fixed in tinytag 2.3.0, by reusing the primary atom parsing code path that contains appropriate size checks.
No workarounds exist. Users must upgrade to tinytag 2.3.0.
