Hi,

The following vulnerability was published for libimager-perl.

CVE-2026-14454[0]:
| Imager versions before 1.033 for Perl treat unsigned EXIF IFD entry
| counts as signed.  Imager mishandled large EXIF IFD entry count
| values, treating them as negative numbers.  This could lead to an
| attempt to allocate a block nearly the size of the address space,
| which fails and kills the process.  An attacker could craft an image
| with EXIF data that terminates a worker process.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
