SCA: security update for pillow (GHSA-4rr5-89j8-mwwm)

medium Tenable Cloud Security Plugin ID 476601

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Pillow is a Python imaging library. From 11.3.0 until 13.0.0, Pillow has a heap use-after-free when
 libtiff rejects a tag while encoding TIFF data to an in-memory buffer. When an application saves attacker-
 influenced TIFF tags to BytesIO, libtiff can reject a tag during encoding in ImagingLibTiffEncode; the
 error path then frees the output buffer without closing or clearing the TIFF handle, and later cleanup
 flushes through the write callback into freed memory, which can crash the process and may enable code
 execution. This issue is fixed in version 13.0.0. (CVE-2026-112396)

Solution

Update the pillow library and its related packages to version 13.0.0 or later.
