 Package : dcmtk Version : 3.6.5-1+deb11u6 CVE ID : CVE-2025-14607 CVE-2025-14841 Debian Bug : 1122926 1123584

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

 CVE-2025-14607

 Possible memory corruption caused by illegal attributes in datasets which are processed by DcmByteString functions.

 CVE-2025-14841

 Invalid messages sent to dcmqrscp, the Image Central Test Node, may trigger a segmentation fault due to a NULL pointer being de-referenced.

 For Debian 11 bullseye, these problems have been fixed in version 3.6.5-1+deb11u6.

 We recommend that you upgrade your dcmtk packages.
