An improper array index validation vulnerability exists in the determineMinMax functionality of OFFIS DCMTK 3.6.8. A specially crafted DICOM file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability.

An improper array index validation vulnerability exists in the nowindow functionality of OFFIS DCMTK 3.6.8. A specially crafted DICOM file can lead to an out-of-bounds write. An attacker can provide a malicious file to trigger this vulnerability.

An incorrect type conversion vulnerability exists in the DVPSSoftcopyVOI_PList::createFromImage functionality of OFFIS DCMTK 3.6.8. A specially crafted malformed file can lead to arbitrary code execution. An attacker can provide a malicious file to trigger this vulnerability.

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.

DCMTK through 3.6.6 does not handle string copy properly. Sending specific requests to the dcmqrdb program, it would query its database and copy the result even if the result is null, which can incur a head-based overflow. An attacker can use it to launch a DoS attack.

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.

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.

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.

OFFIS DCMTK's (All versions prior to 3.6.7) service class user (SCU) is vulnerable to relative path traversal, allowing an attacker to write DICOM files into arbitrary directories under controlled names. This could allow remote code execution.
