Technical details

A heap-based buffer overflow vulnerability (CWE-122) exists in OFFIS DCMTK version 3.7.0. The flaw is located in the DcmQueryRetrieveIndexDatabaseHandle::deleteOldestImages function within the dcmqrdb/libsrc/dcmqrdbi.cc file, which is part of the dcmqrscp (DICOM query/retrieve SCP) component. A remote attacker with low privileges can trigger this overflow by manipulating database queries or image management requests. Successful exploitation could lead to memory corruption, resulting in a denial-of-service condition or potentially remote code execution. A patch (commit 0f78a4ef6f645ea5530166e445e5436a5de58e75) has been released to address this issue.
