CVE-2018-17794 [MEDIUM] CWE-476 binutils: NULL pointer dereference in libiberty/cplus-dem.c:work_stuff_copy_to_from() via crafted input
binutils: NULL pointer dereference in libiberty/cplus-dem.c:work_stuff_copy_to_from() via crafted input
An issue was discovered in cplus-dem.c in GNU libiberty, as distributed in GNU Binutils 2.31. There is a NULL pointer dereference in work_stuff_copy_to_from when called from iterate_demangle_function.
Statement: This issue is classified with a low severity primarily because binutils is not typically exposed to untrusted inputs in most environments, limiting the possibility of exploitation. Additionally, this NULL pointer dereference is only triggered during the parsing of a specially crafted file, requiring an attacker to convince a user to process this file with c++filt. Furthermore, binutils does not handle privileged operations, meaning that exploitation is unlikely to lead to syste
