Pillow is a Python imaging library. Prior to 13.0.0, MpoImageFile.seek() and DcxImageFile.seek() reparse later MPO or DCX frames and replace self._size without rerunning Image._decompression_bomb_check(). A crafted multi-frame image can use a tiny first frame to pass Image.open() and then declare an over-limit later frame. Normal frame iteration through seek(), load(), or ImageSequence.Iterator can decode that frame and commit hundreds of megabytes or more, causing memory-exhaustion denial of service. 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.
