CVE-2022-0546

Memory corruption via missing image bounds check

Published Feb 24, 2022 · Updated Aug 2, 2024

Out-of-bounds heap access in the image loader in Blender 3.x and 2.93.8 allows attackers to corrupt memory or crash through an image. The image loader omits a required bounds check while processing untrusted image data, permitting access beyond its allocated heap buffer. Reaching the flaw requires user interaction to load the image; confirmed consequences are memory corruption and a process crash.
