Upgrade pillow to version 13.0.0 or higher.
Overview
Affected versions of this package are vulnerable to Infinite loop via incorrect initialization of _n_frames and is_animated in TiffImagePlugin.TiffImageFile, where _n_frames was set inside _open() rather than __init__(), allowing it to be overwritten by a MicImageFile subclass. An attacker can supply a multi-frame TIFF (or MIC) image that causes _n_frames and is_animated to be set to incorrect values, leading to a crash when iterating frames.
Note: This is only exploitable if the optional olefile package is installed.
