Notes
| Author | Note |

| seth-arnold | binutils isn't safe for untrusted inputs. |
| ccdm94 | according to the patch referenced in the issue, the dereference happens when the 'debug_info_p' variable is referenced but not set in a 'fetch_indexed_string' call, in 'read_and_display_attr_value'. In bionic and earlier, these specific calls (referenced in the patch) are not made sending 'debug_info_p' as an argument. |
