Several vulnerabilities have been fixed in DCMTK, a collection of
libraries and applications implementing large parts of the DICOM standard
for medical images.

CVE-2025-9732

    Processing of an invalid DICOM image with a Photometric
    Interpretation of "YBR_FULL" and a Planar Configuration of "1" where
    the number of pixels stored does not match the expected number of pixels.
    This may lead to memory corruption.

CVE-2022-4981

    Various issues in the dcmqrscp configuration file parser that could cause
    application crashes when reading a malformed configuration file, due to
    insufficient checks of the input data.

CVE-2020-36855

    Stack-based overflow in the dcmqrscp config parser.
    

For Debian 11 bullseye, these problems have been fixed in version
3.6.5-1+deb11u5.

We recommend that you upgrade your dcmtk packages.
