Comment 2 Sandro Mani 2023-08-28 21:03:22 UTC

I'm assuming this should read FreeImage before *3.18.0*? And where is it stated that only < 3.18.0 is affected? I can't find or deduce this information from the upstream report.

Comment 3 Guilherme de Almeida Suckevicz 2023-08-29 14:07:08 UTC

Hi, the CVE description probably meant 3.18.0, this is the way it's in the Mitre CVE page[1] though.

I don't have affected information and the report is not very clear. However, given the upstream issue is still opened and the vulnerable code is present in 'trunk', I would say all versions before and including 3.18.0 are affected.
