Pillow is a Python imaging library. Prior to 13.0.0 on Windows, src/PIL/WmfImagePlugin.py passes unchecked 32-bit WMF or EMF dimensions to the native drawwmf handler in src/display.c. The handler sizes a DIB allocation from 16-bit-truncated bcWidth and bcHeight fields but copies pixel data using the original full dimensions. A crafted wide, short metafile can pass the pixel-count decompression-bomb check and make the Windows-only renderer read beyond the heap buffer, potentially disclosing memory or crashing the process. 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. Prior to 13.0.0 on Windows, src/PIL/WmfImagePlugin.py passes unchecked
    32-bit WMF or EMF dimensions to the native drawwmf handler in src/display.c. The handler sizes a DIB
    allocation from 16-bit-truncated bcWidth and bcHeight fields but copies pixel data using the original full
    dimensions. A crafted wide, short metafile can pass the pixel-count decompression-bomb check and make the
    Windows-only renderer read beyond the heap buffer, potentially disclosing memory or crashing the process.
    This issue is fixed in version 13.0.0. (CVE-2026-96644)

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