Doc Text:
A heap-based buffer overflow flaw was found in Ghostscript’s GhostPDL in the sampled_data_finish function (called from sampled_data_continue and interp). This flaw allows a local attacker to pass a specially crafted malicious file to Ghostscript that triggers a heap-based buffer overflow, potentially causing a crash that leads to a denial of service.

Comment 1 Michael J Gruber 2022-02-01 14:25:12 UTC
Fedora versions all the way down to F33 are not affected - they carry  ghostscript-9.55.0.

So, which version are you reporting this against?
