Description

As a part of medical infrastructure security research, the DeteAct Team started to perform fuzzing of various open source medical data processing libraries.
During fuzzing of the dcm2pnm utility, a memory corruption (buffer overflow) bug was found, which occurs in DcmRLEDecoder::decompress() (file dcrledec.h, line 122). Attached are three sample files that trigger the (same) bug when processed with either dcm2pnm or dcmdrle.

Reported 2018-11-27 by Omar Ganiev <>, DeteAct Team, Open Medical Infrastructure Security Project.
