CVE-2026-112202 · Severity: info · Published 2026-10-20

Imager::File::GIF is a Perl library for reading and manipulating image files, including GIF format. When processing GIF images with the consolidation feature enabled, an attacker can craft a malicious GIF file to read memory from the application's heap and potentially crash the process. This could lead to information disclosure or denial of service.

## How to fix

- Fixed in Imager::File::GIF 1.006 and later

## Technical details

An out-of-bounds read vulnerability exists in the i_readgif_low routine when gif_consolidate is enabled. Palette indices from a GIF image are used without bounds checking against the color table, allowing reads beyond the allocated heap buffer. The vulnerability affects Imager::File::GIF as a standalone module and the bundled GIF reader in the Imager distribution; the default GIF reader without consolidation is not affected.

## Affected products

- Tony Cook Imager::File::GIF before 1.006
- Tony Cook Imager versions with bundled GIF code before the patch date

## Timeline

- 2026-10-20: disclosed
