Pillow is a Python imaging library. From 11.2.1 until 13.0.0, Arrow export assumes that an image's rows are tightly contiguous and exports from im->blocks[0].ptr even when PILLOW_ALIGNMENT makes aligned_linesize include row padding or an aligned offset before the first row. The resulting Arrow buffer can include uninitialized padding, bytes preceding the first row, or stale heap contents from previously freed images. Applications that configure alignment and export images to Arrow can therefore disclose one user's pixels or other process memory to another user. 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 11.2.1 until 13.0.0, Arrow export assumes that an image's rows
    are tightly contiguous and exports from im->blocks[0].ptr even when PILLOW_ALIGNMENT makes
    aligned_linesize include row padding or an aligned offset before the first row. The resulting Arrow buffer
    can include uninitialized padding, bytes preceding the first row, or stale heap contents from previously
    freed images. Applications that configure alignment and export images to Arrow can therefore disclose one
    user's pixels or other process memory to another user. This issue is fixed in version 13.0.0.
    (CVE-2026-114501)

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