Summary
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.

Fencer Intel keeps one entry per vulnerability: the CVE id wins, then GHSA, and records that alias each other are merged, except that two CVEs always keep separate entries. The same data is available as JSON.
CPEs and fixed versions use Anchore's correction of NVD's data: Added CPE configurations because not yet analyzed by NVD.
