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.

The remote Fedora 44 host has a package installed that is affected by a vulnerability as referenced in the FEDORA-2026-5f5efe281d advisory.

    1.033
    - CVE-2026-14454: Fix mishandling of large EXIF IFD entry count values  treated as negative numbers,     could lead to allocation failure and program exit
    - JPEG: depend on Imager 1.033 for the EXIF fix
    - Fix thread context object reference count leak in bumpmap and bumpmap_complex filters
    - TIFF: fix a leak from processing the TIFF warnings buffer (introduced in Imager 1.021)

Tenable has extracted the preceding description block directly from the Fedora security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
