A fixed version on one release line is not the upgrade target for every line. Check your exact version and any vendor backports.
Description
Imager versions before 1.037 for Perl exit the process reading a raw image with an out-of-range raw_datachannels value in i_readraw_wiol.
Nothing range-checks raw_datachannels. The line buffer is sized as the image width times the channel count with no overflow check, so a negative or very large count requests an excessive allocation. When it fails, Imager's allocator calls exit(3).
Passing an untrusted raw_datachannels value to Imager->read() triggers an uncatchable exit.
