  script_tag(name:"insight", value:"A security vulnerability was identified in Orthanc, a DICOM server used for medical imaging, whereby authenticated API users had the capability to overwrite arbitrary files and, in certain configurations, execute unauthorized code.

This update addresses the issue by backporting a safeguard mechanism: the RestApiWriteToFileSystemEnabled option is now included, and it is set to true by default in the /etc/orthanc/orthanc.json configuration file. Should users wish to revert to the previous behavior, they can manually set this option to true themselves.

For Debian 10 buster, this problem has been fixed in version 1.5.6+dfsg-1+deb10u1.

We recommend that you upgrade your orthanc packages.

For the detailed security status of orthanc please refer to its security tracker page at: [link moved to references]

Further information about Debian LTS security advisories, how to apply these updates to your system and frequently asked questions can be found at: [link moved to references]");
