NVD Description

Note: Versions mentioned in the description apply only to the upstream python313-Pillow package and not the python313-Pillow package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

Pillow is a Python imaging library. Prior to 12.3.0, when Pillow loads an uncompressed McIdas AREA image from a filename through the mmap raw codec path, attacker-controlled header words can set a row stride smaller than the natural row width, causing pixel access such as Image.tobytes(), getpixel, convert, or save to read beyond the mapped region and disclose adjacent process memory or fault. This issue is fixed in version 12.3.0.
