Fedora 42 python-pydicom Moderate Path Traversal Risk CVE-2026-32711

pydicom is a pure python package for working with DICOM files. It was made for

inspecting and modifying DICOM data in an easy "pythonic" way. The

modifications can be written again to a new file.

pydicom is not a DICOM server, and is not primarily about viewing images. It is

designed to let you manipulate data elements in DICOM files with python code.

Limitations -- the main limitation of the current version is that compressed

pixel data (e.g. JPEG) cannot be altered in an intelligent way as it can for

uncompressed pixels. Files can always be read and saved, but compressed pixel

data cannot easily be modified.
