Описание
An out-of-bounds write vulnerability exists in the Grassroots DICOM library (GDCM). The issue is triggered during parsing of a malformed DICOM file containing encapsulated PixelData fragments (compressed image data stored as multiple fragments). This vulnerability leads to a segmentation fault caused by an out-of-bounds memory access due to unsigned integer underflow in buffer indexing. It is exploitable via file input, simply opening a crafted malicious DICOM file is sufficient to trigger the crash, resulting in a denial-of-service condition.
A flaw was found in the Grassroots DICOM library (GDCM). A remote attacker could exploit an out-of-bounds write vulnerability by tricking a user into opening a specially crafted DICOM file. This file, containing malformed image data, triggers an unsigned integer underflow during parsing, leading to an out-of-bounds memory access. Successful exploitation results in a denial-of-service condition, causing the application to crash.
Отчет
This vulnerability is rated Moderate. An out-of-bounds write flaw in the Grassroots DICOM (GDCM) library can be triggered by parsing a specially crafted DICOM file. This can lead to a denial-of-service condition. Exploitation requires user interaction, as a victim must open a malicious DICOM file.
