Upgrade Debian:unstable libimager-perl to version 1.037+dfsg-2 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream libimager-perl package and not the libimager-perl package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
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.
