dev-lang/orc < 0.4.40 >= 0.4.40
Impact
It is possible for a malicious third party to trigger a buffer overflow
and effect code execution with the same privileges as the orc compiler
is called with by feeding it with malformed orc source files.
This only affects developers and CI environments using orcc, not users of liborc.
