Ubuntu Security Notice 7010-1 - Jinsheng Ba discovered that DCMTK incorrectly handled certain requests. If a user or an automated system were tricked into opening a certain specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 20.04 LTS. Sharon Brizinov and Noam Moshe discovered that DCMTK incorrectly handled pointers. If a user or an automated system were tricked into opening a certain specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 20.04 LTS.
DCMTK v3.6.7 was discovered to contain a memory leak via the T_ASC_Association object.
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.
OFFIS DCMTK's (All versions prior to 3.6.7) has a NULL pointer dereference vulnerability while processing DICOM files, which may result in a denial-of-service condition.
