AI-suggested
If you cannot patch yet, avoid processing untrusted paletted images with Imager versions prior to 1.036 to prevent potential memory disclosure.
Description
Imager versions before 1.036 for Perl contain a vulnerability where reading a paletted image with pixel indexes beyond the color map causes uninitialized heap memory disclosure. The palette is allocated without initialization, and pixel indexes equal to the palette size read unpopulated entries, leaking prior heap contents. This occurs when reading attacker-supplied images and then fetching pixels or converting them to RGB.
