It was reported that a number of dcmtk utilities did not handle setuid() failures. If the setuid() call failed, the utilities would continue running with elevated privileges, possibly leading to privilege escalation.
The original report notes the following limitations:
- the tool is installed with suid bit
- the tool is run from an unprivileged user
- the kernel is configured to limit the number of processes per user
From looking at the spec file, it seems the suid bit is not used, so these may not be exploitable on Fedora.
