https://github.com/gpac/gpac/commit/328c6d682698fdb9878dbb4f282963d42c538c01 (v2.0.0)
https://github.com/gpac/gpac/issues/1756
The POC from the GitHub issue produces a SIGSEV in the stretch/buster version of gpac, but in an entirely different call chain; it appears to be a different issue altogether
It isn't clear if that means this CVE doesn't apply to stretch/buster, or if it is masking the issue with an earlier failure
