CVE-2026-87020 Orthanc DICOM Server Integer Overflow or Wraparound

An integer overflow in a specified pitch and buffer-size computation leads to a heap out-of-bounds write when Orthanc DICOM Server decodes an attacker-supplied PNG...

CVE-2026-87020

Orthanc DICOM Server (headquartered in Belgium, deployed worldwide in the healthcare sector) is vulnerable to an integer overflow in its pitch and buffer-size computation when decoding an attacker-supplied PNG or JPEG image. This leads to a heap out-of-bounds write , resulting in a process crash ...

Orthanc DICOM Server

ADVISORY SUMMARY Successful exploitation of this vulnerability could allow an authenticated remote attacker to write past the end of a heap allocation when Orthanc decodes an attacker-supplied PNG or JPEG image, resulting in a crash of the Orthanc process and a denial-of-service condition. 2...

TRC analysis shows authenticated attackers are exploiting CVE-2026-87020 to crash Orthanc DICOM servers by uploading malicious PNG/JPEG images. The integer overflow triggers heap corruption, disrupting medical imaging operations across healthcare facilities. Healthcare Vulnerability :link: Full...

Astra Linux – Vulnerability in dcmtk

The service class provider SCP of OFFIS DCMTK all versions prior to 3.6.7 is vulnerable to path traversal attacks, allowing attackers to write DICOM files into arbitrary directories under controlled names. This could enable remote code execution...

Astra Linux – Vulnerability in dcmtk

A vulnerability was detected in DCMTK up to version 3.6.7. The affected element is the function DcmQueryRetrieveConfig::readPeerList in the file /dcmqrcnf.cc of the component dcmqrscp. This vulnerability results in a null pointer dereference. The attack can be carried out locally. The exploit is...

Astra Linux – Vulnerability in dcmtk

A vulnerability was identified in DCMTK up to version 3.6.9. This affects an unknown function in the library dcmimage/include/dcmtk/dcmimage/diybrpxt.h of the component dcm2img. Such manipulation leads to memory corruption. Local access is required to exploit this attack. The name of the patch is...

Astra Linux – Vulnerability in dcmtk

The service class user SCU of OFFIS DCMTK all versions prior to 3.6.7 is vulnerable to relative path traversal, allowing an attacker to write DICOM files into arbitrary directories under controlled names. This could enable remote code execution...

Astra Linux – Vulnerability in dcmtk

DCMTK’s version 3.6.6 does not handle memory release properly. The memory allocated for storing all file information is stored in a global variable called LST, and this memory is not released properly. Making specific requests to the dcmqrdb program can lead to a memory leak. An attacker can use...

OFFIS DCMTK’s all versions prior to 3.6.7 has a NULL pointer dereference vulnerability when processing DICOM files, which may lead to a denial-of-service condition...

Astra Linux – Vulnerability in gdcm

There is a heap-based buffer overflow vulnerability in the LookupTable::SetLUT functionality of Mathieu Malaterre Grassroot DICOM 3.0.23. A specially crafted, malformed file can lead to memory corruption. An attacker can provide a malicious file to exploit this vulnerability...

Astra Linux – Vulnerability in dcmtk

DCMTK through version 3.6.6 does not handle string copying properly. When specific requests are sent to the dcmqrdb program, it queries its database and copies the result, even if the result is null. This can lead to a head-based overflow. An attacker can use this vulnerability to launch a DoS...

CVE-2026-40509

OpenEMR before 8.3.0 contains a cross-site request forgery vulnerability in the DICOM viewer. The webpath GET parameter in the DICOM viewer page is embedded unsanitized as a URL without validation against expected path formats. An attacker can craft a URL that causes an authenticated user with...
