CVE-2026-4152

Code execution via unchecked JP2 length

Published Apr 11, 2026 · Updated Apr 11, 2026

Heap-based buffer overflow in GIMP 3.0.8 allows remote attackers to execute arbitrary code through a crafted JP2 file. The JP2 parser copies user-supplied data into a heap buffer without validating that its encoded length fits the destination. Execution requires the target to open the file or visit a page that causes GIMP to process it, and code runs in the current process.
