description

Pillow versions from 9.4.0 through versions before 13.0.0 can overflow a heap buffer while re-saving a JPEG that combines crafted metadata with an ICC color profile. An attacker who can supply such an image to an application that re-encodes it as JPEG while preserving the profile may crash the Python process and could potentially achieve code execution.

mitigation

Upgrade Pillow to version 13.0.0 or later. Until upgraded, avoid re-encoding untrusted images as JPEG while preserving embedded ICC profiles or comments.

fixed in 13.0.0
