Pillow is a Python imaging library. From 11.0.0 until 13.0.0, multi-frame loaders can retain an ImagingCore allocation created for a narrow frame mode while a later frame of the same dimensions changes the logical mode and decoder tiles to wider RGB or CMYK data. ImageFile.load_prepare() reuses the stale native storage because _im is non-null without verifying that its mode and size still match. Crafted PSD, MPO, DCX, or MIC frame transitions can then write wider pixels into the narrow allocation, causing native out-of-bounds writes and crashes. The MPO path can also cause a native over-read and, in demonstrated runtime-specific profiles, command execution. This issue is fixed in version 13.0.0.

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the b9a3fd21-d2af-11f1-bae2-3497f65b111b advisory.

    The Pillow project published security advisories for issues fixed               in release 13.0.0.  They include an argument injection in the               Ghostscript call used for EPS images, heap buffer overflows in               several image decoders that can lead to code execution, and               infinite loops and unbounded memory use when opening crafted               image files.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

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

  - Pillow is a Python imaging library. From 11.0.0 until 13.0.0, multi-frame loaders can retain an
    ImagingCore allocation created for a narrow frame mode while a later frame of the same dimensions changes
    the logical mode and decoder tiles to wider RGB or CMYK data. ImageFile.load_prepare() reuses the stale
    native storage because _im is non-null without verifying that its mode and size still match. Crafted PSD,
    MPO, DCX, or MIC frame transitions can then write wider pixels into the narrow allocation, causing native
    out-of-bounds writes and crashes. The MPO path can also cause a native over-read and, in demonstrated
    runtime-specific profiles, command execution. This issue is fixed in version 13.0.0. (CVE-2026-96639)

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.
