7.5HIGH
What is CVE-2021-41688?
DCMTK versions up to 3.6.6 exhibit improper memory handling, where an object can be freed while its address is still referenced by other parts of the application. This flaw can be exploited by sending specifically crafted requests to the dcmqrdb program, potentially resulting in a double free scenario. An attacker could leverage this weakness to cause denial of service, interrupting the functionality of the service dependent on DCMTK.
