Summary: CVE-2026-102505 perl-Imager: perl-Imager: Arbitrary
code execution via heap-based buffer overflow in
paletted image processing [fedora-all]
Product: Fedora
Version: rawhide
Status: NEW

Target Milestone: ---
Classification: Fedora
Disclaimer: Community trackers are created by Red Hat Product Security team on
a best effort basis. Package maintainers are required to ascertain if the flaw
indeed affects their package, before starting the update process.
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.
