Doc Text:
A heap-use-after-free flaw was found in Ghostscript’s GhostPDL in the sampled_data_sample 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-use-after-free issue, potentially causing a crash that leads to a denial of service.

Comment 1 Michael J Gruber 2022-02-01 14:25:02 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?
Comment 4 Marian Rehak 2022-02-03 18:26:28 UTC 
Yes, and fedora is filed as notaffected + no trackers, what is your problem here?

"Version unspecified" "OS Linux"

Where is Fedora filed as notaffected?

If it's not filed against Fedora, why am I on cc?


> what is your problem here?

I had a simple and fair question.

The "problem" is the tone of your response.
