Description Pedro Sampaio 2018-11-22 17:36:06 UTC 
An issue was discovered in cp-demangle.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a stack consumption problem caused by the cplus_demangle_type function making recursive calls to itself in certain scenarios involving many 'P' characters.

This looks like yet another duplicated stack exhaustion flaw in libiberty.
