SCA: security update for pillow (GHSA-4rm8-3hmm-39fg)

medium Tenable Cloud Security Plugin ID 476869

Description

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

 - Pillow is a Python imaging library. Prior to 13.0.0, PILfont text-width accumulation in src/_imaging.c
 checks positive glyph advances against INT_MAX but does not check negative advances against INT_MIN.
 Repeating a signed 16-bit advance of -32768 can therefore execute a signed C integer overflow in xsize +=
 dx, producing a large positive width from a negative mathematical result. Applications that use
 getlength(), getsize(), or derived layout, quota, serialization, or allocation calculations can experience
 logic-integrity errors or resource consumption, while the high-level mask path commonly retains a
 decompression-bomb check. This issue is fixed in version 13.0.0. (CVE-2026-96641)

Solution

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