CVE-2025-14423

Code execution via unchecked LBM data length

Published Dec 23, 2025 · Updated Dec 23, 2025

Stack-based buffer overflow in GIMP 3.0.6 allows remote attackers to execute arbitrary code after a user opens a crafted LBM file. The LBM parser copies user-supplied data into a stack buffer without first validating that the data length fits the destination. Exploitation requires user interaction and runs attacker-controlled code in the context of the GIMP process.
