Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

MONAI (PyPI package monai) versions before 1.6.1 are affected: crafted DICOM files with NaN or infinity values in spatial fields such as PixelSpacing can pass through pydicom and MONAI's PydicomReader. An unauthenticated attacker with network access to a MONAILabel server, using its default REST API, can upload such a file and trigger inference, which can crash the server or silently produce corrupted results. Upgrade monai to version 1.6.1 or later, which is the fixed version listed in the advisory.
