Heap-based buffer overflow in OFFIS DCMTK's XMLNode::parseFile function (ofstd/libsrc/ofxml.cc) affects all versions through 3.7.0, exploitable by any remote party who can supply a crafted or non-seekable XML input to the parser. The root cause - confirmed by the upstream patch commit - is that the original guard `if (!l)` failed to catch a -1 return from ftell(), allowing a corrupted buffer size to propagate into heap allocation and subsequent write. A public proof-of-concept exploit exists per VulDB and a published Medium writeup; no active exploitation is confirmed via CISA KEV. The CVSS 4.0 score of 2.1 reflects passive-interaction and low-impact ratings, but the presence of public exploit code elevates practical risk for any DCMTK deployment that parses externally influenced XML files.
Heap-based buffer overflow in OFFIS DCMTK 3.7.0's dcmqrscp component allows remote low-privileged attackers to trigger memory corruption via the deleteOldestImages function in the DICOM Query/Retrieve database backend. Exploitation requires authenticated network access with low complexity and results in partial confidentiality, integrity, and availability impact without crossing privilege boundaries. No public exploit identified at time of analysis; an upstream git commit patch is confirmed available, though a formally tagged release version incorporating the fix has not been independently verified.
OS command injection in OFFIS DCMTK's storescp utility (versions up to 3.7.0) allows unauthenticated remote attackers to execute arbitrary system commands via crafted DICOM network operations. The vulnerability resides in the executeOnReception and executeOnEndOfStudy functions within dcmnet/apps/storescp.cc. With a CVSS score of 7.3 and network attack vector requiring no authentication, this presents significant risk to medical imaging systems using vulnerable DCMTK versions. Vendor patch edbb085e45788dccaf0e64d71534cfca925784b8 is available; no public exploit identified at time of analysis.
