UBUNTU-CVE-2021-41690
DCMTK through 3.6.6 does not handle memory free properly. The malloced memory for storing all file information are recorded in a global variable LST and are not freed properly. Sending specific requests to the dcmqrdb program can incur a memory leak. An attacker can use it to launch a DoS attack...
CVE-2021-41687
DCMTK has a memory free issue in versions up to 3.6.6 (CVE-2021-41687) where allocated heap memory during parsing may not be freed on parsing errors, enabling a DoS via crafted requests to dcmqrdb. Public advisories (Ubuntu USN-7010-1, Debian DLA-4038-1, Debian 10/DLA-3847, Mageia MGASA-2024-0251...
CVE-2021-41687
DCMTK through 3.6.6 does not handle memory free properly. The program malloc a heap memory for parsing data, but does not free it when error in parsing. Sending specific requests to the dcmqrdb program incur the memory leak. An attacker can use it to launch a DoS attack...
CVE-2021-41688
DCMTK through 3.6.6 does not handle memory free properly. The object in the program is free but its address is still used in other locations. Sending specific requests to the dcmqrdb program will incur a double free. An attacker can use it to launch a DoS attack...
CVE-2021-41688
CVE-2021-41688 affects DCMTK up to version 3.6.6, where improper memory management in DCMTK’s dcmqrdb handling can lead to a double free and a resulting denial of service. The vulnerability is described as: an object is freed while its address remains in use, allowing specific requests to trigger...
