Overview

CVE-2026-112202 is a medium-severity vulnerability. It was published on October 20, 2026 and has a CVSS 3.1 base score of 6.5 (MEDIUM).

This vulnerability has a CVSS 3.1 base score of 6.5, rated MEDIUM. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

Imager::File::GIF versions before 1.006 for Perl allow out-of-bounds reads when consolidating GIF images.

With `gif_consolidate => 1`, palette indices from the image are used without checking the colour table's bounds. The i_readgif_low routine reads beyond the heap allocation and copies the bytes into output pixels. The default GIF reader is not affected.

The same code ships bundled in the Imager distribution.

An attacker supplying a crafted GIF can disclose adjacent heap memory through the decoded output and may crash the process.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
