    Debian Bug     : 1144349

    Multiple vulnerabilities were discovered in FreeCAD, a parametric 3D CAD
    modeller, which may result in the execution of arbitrary code, the
    disclosure of local files or requests to arbitrary hosts when a crafted
    FCStd document or template is processed.

    For the stable distribution (trixie), these problems have been fixed in
    version 1.0.0+dfsg-8+deb13u3.

    We recommend that you upgrade your freecad packages.

    For the detailed security status of freecad please refer to
    its security tracker page at:
    https://security-tracker.debian.org/tracker/freecad
