Routine

MEDIUM 6.3UPGRADE

CVE-2026-102505 is a medium-severity flaw (CVSS 6.3) affecting imager. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Imager versions before 1.037 for Perl overflow a heap buffer fetching float samples from a paletted image in i_gsampf_fp. For a paletted image, getsamples() with type "float" allocates a buffer of one sample per pixel and fetches every requested channel of each pixel into it. Requesting more than one channel writes past its end. An attacker-supplied image controls the overflowing bytes through its palette.

Why this priority

No elevated risk signals yet

A fixed release or distro patch exists.
