DEBIAN-CVE-2026-5442

A heap buffer overflow vulnerability exists in the DICOM image decoder. Dimension fields are encoded using Value Representation VR Unsigned Long UL, instead of the expected VR Unsigned Short US, which allows extremely large dimensions to be processed. This causes an integer overflow during frame...

CVE-2026-5437

An out-of-bounds read vulnerability exists in DicomStreamReader during DICOM meta-header parsing. When processing malformed metadata structures, the parser may read beyond the bounds of the allocated metadata buffer. Although this issue does not typically crash the server or expose data directly ...

CVE-2026-5441

An out-of-bounds read vulnerability exists in the DecodePsmctRle1 function of DicomImageDecoder.cpp. The PMSCTRLE1 decompression routine, which decodes the proprietary Philips Compression format, does not properly validate escape markers placed near the end of the compressed data stream. A crafte...

CVE-2026-5444

A heap buffer overflow vulnerability exists in the PAM image parsing logic. When Orthanc processes a crafted PAM image embedded in a DICOM file, image dimensions are multiplied using 32-bit unsigned arithmetic. Specially chosen values can cause an integer overflow during buffer size calculation,...

CVE-2026-5443

A heap buffer overflow vulnerability exists during the decoding of PALETTE COLOR DICOM images. Pixel length validation uses 32-bit multiplication for width and height calculations. If these values overflow, the validation check incorrectly succeeds, allowing the decoder to read and write to memor...

UBUNTU-CVE-2026-5445

An out-of-bounds read vulnerability exists in the DecodeLookupTable function within DicomImageDecoder.cpp. The lookup-table decoding logic used for PALETTE COLOR images does not validate pixel indices against the lookup table size. Crafted images containing indices larger than the palette size...
