Description Andrej Nemec 2016-05-05 07:50:57 EDT

A bug was found in libiberty. A stack overflow in the libiberty demangler library causes its host applications to crash. Not considered security bug because it's a stack overflow, leading to a SIGSEGV because it lacks memory to continue the faulty recursive function.
