CVE-2026-2049

Code execution via unchecked HDR scanline length

Published Jun 10, 2026 · Updated Jun 10, 2026

Heap-based buffer overflow in GIMP 3.2.0-RC1 allows remote attackers to execute code by inducing a user to open a crafted HDR file. The rgbe_read_new_rle function copies attacker-controlled run-length data into a heap buffer without validating the encoded length. Exploitation requires user interaction and runs code with the privileges of the GIMP process on the affected desktop.
