HIGH 7.5REMOTEUPGRADE

CVE-2026-102504 is a high-severity flaw (CVSS 7.5) affecting imager. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

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()
