This would seem to be issue in libjpeg and not in jpegoptim?

@tjko thanks, I have reported the issue to libjpeg-turbo, wait for their reply

referring the comment,
https://github.com/libjpeg-turbo/libjpeg-turbo/security/advisories/GHSA-mm58-28hq-3c32#advisory-comment-93367
It will check with the latest jpegoptim version of v1.5.5

@tjko there are no more SEGV crashes using the same POC with jpegoptim v1.5.5, I suppose the issue was already fixed by 3401f25
It seems to be the same issue with
#107
CVE-2022-32325

@schsiung, yes I think you're correct. I had forgotten about the 'custom' memory manager that jpegoptim uses. It can make it look like there is problem in the libjpeg, when the problem is actually in jpegoptim (jpegsrc.c)...
