Hi, The following vulnerability was published for gdcm. CVE-2025-11266[0]: | An out-of-bounds write vulnerability exists in the Grassroots DICOM | library (GDCM). The issue is triggered during parsing of a malformed | DICOM file containing encapsulated PixelData fragments (compressed | image data stored as multiple fragments). This vulnerability leads | to a segmentation fault caused by an out-of-bounds memory access due | to unsigned integer underflow in buffer indexing. It is exploitable | via file input, simply opening a crafted malicious DICOM file is | sufficient to trigger the crash, resulting in a denial-of-service | condition. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
