Machine-written summary

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

GHSA-px68-xx5g-48q5 affects the dcmjs npm package versions before 0.52.0. Malformed DS (Decimal String) and IS (Integer String) DICOM values can be parsed into JavaScript Infinity or NaN, and IS values can use scientific notation that the standard does not allow. The source describes the input as a DICOM field with crafted values and does not clearly state what access is required; it says the maintainer rates the impact as low. Upgrade to dcmjs 0.52.0 or later.
