CVE-2023-32134

Arbitrary code execution via DCM parser use-after-free

Published May 3, 2024 · Updated Aug 15, 2024

Use-after-free in Santesoft LTD Sante DICOM Viewer Pro 11.8.11.0 allows remote attackers to execute code via a crafted DCM image. The DCM image parser performs operations on an object without first validating that the object still exists, leaving a freed object reference usable. Exploitation requires a user to visit a malicious page or open a malicious file, and successful exploitation runs code in the current process.
