CWE-400  (opens in a new tab)

How to fix?

Upgrade Alpine:3.23 py3-pillow to version 8.1.2-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream py3-pillow package and not the py3-pillow package as distributed by Alpine. See How to fix? for Alpine:3.23 relevant fixed versions and status.

Pillow before 8.1.2 allows attackers to cause a denial of service (memory consumption) because the reported size of a contained image is not properly checked for an ICNS container, and thus an attempted memory allocation can be very large.
