Grassroots DICOM Missing release of memory after effective lifetime
A memory leak exists in the Grassroots DICOM library (GDCM). The bug occurs when parsing malformed DICOM files with non-standard VR types in file meta information. The vulnerability leads to vast memory allocations and resource depletion, triggering a denial-of-service condition. A maliciously crafted file can fill the heap in a single read operation without properly releasing it.
An out-of-bounds read vulnerability exists in the JPEGBITSCodec::InternalCode functionality of Grassroot DICOM 3.024. A specially crafted DICOM file can lead to an information leak. An attacker can provide a malicious file to trigger this vulnerability.The function `null_convert` is called based of the value of the malicious DICOM file specifying the intended interpretation of the image pixel data
