Name of the Vulnerable Software and Affected Versions Pillow versions prior to 12.3.0

Description When loading an uncompressed McIdas AREA image from a filename using the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width. This leads to out-of-bounds reads when accessing pixels via functions such as Image.tobytes(), getpixel(), convert(), or save(), which may result in the disclosure of adjacent process memory or a system fault.

Recommendations Update to version 12.3.0.
