CVE-2026-14454
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedImager 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.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceThe Imager Perl library before version 1.033 incorrectly interprets unsigned EXIF IFD entry counts as signed integers. When processing maliciously crafted EXIF data with large entry counts, the library misinterprets them as negative values, triggering an attempt to allocate a massive memory block (nearly the full address space), which fails and terminates the process.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Check installed Imager versionRun `perl -MImager -e 'print $Imager::VERSION'` to display the installed Imager version numberAffected if Version is below 1.033
-
Identify EXIF processing usageSearch application code for Imager functions that handle EXIF data, such as calls to read or parse EXIF tags when loading imagesAffected if Code uses Imager to read or process EXIF metadata from images
-
Determine image source trust levelReview whether Imager processes images from untrusted or external sources such as user uploads, web requests, or network-fetched contentAffected if Imager processes images from untrusted or user-supplied sources that could contain malicious EXIF data
You are affected if Imager version is below 1.033 AND your application uses Imager to process EXIF data from untrusted sources.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped1.033
Upgrade Imager to version 1.033 or later. If immediate patching isn't possible, restrict or validate image uploads before processing, and run Imager in sandboxed environments to limit impact of process termination.
1.033
- Update your Perl module installer (e.g., cpanm or cpan): `cpanm --self-upgrade` or `cpan -T CPAN::Bundle`
- Upgrade Imager to version 1.033 or later using your Perl module installer: `cpanm [email protected]` or `cpaninstall Imager`
- Verify the installed version: `perl -MImager -e 'print Imager->new()->VERSION'
- If using Imager in a deployed application, restart any Perl processes that load Imager to ensure the patched version is loaded
