Not Vulnerable:

GNU Binutils 'readelf.c' Heap Buffer Overflow Vulnerability

GNU Binutils is prone to a heap-based buffer-overflow vulnerability because it fails to adequately bounds-check user-supplied data before copying it into an insufficiently sized buffer.

An attacker can exploit this issue to crash the affected application, resulting in denial-of-service conditions. Due to the nature of this issue, arbitrary code execution may be possible but this has not been confirmed.

GNU Binutils 2.29.1 is vulnerable; other versions may also be affected.
