Both examples seem to point issue in libjpeg.so.8 (what was the exact version of libjpeg that jpegoptim was linked against?)

I use ldconfig -v | grep libjpeg to checkout the version of libjpeg i use ,and the result : libjpeg.so.8 -> libjpeg.so.8.1.2

Was registered as CVE-2022-32325

How exactly is this an issue in jpegoptim?

Stack traces clearly show issue in libjpeg.so.8, and not in jpegoptim.... or am I missing something?

I would suggest to check and reproduce it with a newer "jpegoptim" over updated "libjpeg". Probably it's not an issue anymore. Also not sure if it's applicable to "libjpeg-turbo".

Unable to reproduce with the current 'master' branch (tested with currently latest libjpeg version "9e"):

$ ./jpegoptim -f --all-progressive 'crash1_SEGV_caused_by_READ_memory_access_at_jpegoptim.c^%631^%3'
crash1_SEGV_caused_by_READ_memory_access_at_jpegoptim.c^%631^%3  [ERROR]

$ ./jpegoptim -f --all-progressive 'crash_SEGV_caused_by_READ_memory_access_at_jpegoptim.c^%710^%18'

It could be that this was fixed by change 3401f250ace692a5b23eac1617dc429eb3566f9f.

Can you validate if you can still reproduce issue with the latest version from github?
