Grassroots DICOM (GDCM) is a C++ library for processing DICOM medical
|
|
images.
|
|
It provides routines to view and manipulate a wide range of image formats
|
|
and can be accessed through many popular programming languages like Python,
|
|
C#, Java and PHP.
|
|
|
|
GDCM versions 2.6.0 and 2.6.1 (and possibly previous versions) are prone
|
|
to an
|
|
integer overflow vulnerability which leads to a buffer overflow and
|
|
potentially to remote code execution. The vulnerability is triggered by the
|
|
exposed function gdcm::ImageRegionReader::ReadIntoBuffer, which copies
|
|
DICOM
|
|
image data to a buffer. ReadIntoBuffer checks whether the supplied
|
|
buffer is
|
|
large enough to hold the necessary data, however in this check it fails to
|
|
detect the occurrence of an integer overflow, which leads to a buffer
|
|
overflow
|
|
later on in the code. The buffer overflow will occur regardless of the
|
|
size of
|
|
the buffer supplied to the ReadIntoBuffer call.
|
|
|
|
More information about this vulnerability can be found at
|
|
http://census-labs.com/news/2016/01/11/gdcm-buffer-overflow-imageregionreaderreadintobuffer/
|
|
|
|
The GDCM project has released version 2.6.2 that addresses this issue.
|
|
It is advised to upgrade all GDCM installations to the latest stable
|
|
release.
