Technical details
A 32-bit integer overflow in the thumb_data_vertical_flip() function within the blend file thumbnail extractor allows a heap buffer overflow when processing TEST block dimensions. The vulnerability is triggered via crafted .blend files with malicious dimensions, leading to out-of-bounds writes. An attacker needs a user to preview or open the malicious .blend file; remote code execution is possible.
