Notes
| Author | Note |
|---|---|
| seth-arnold | binutils isn't safe for untrusted inputs. |
| ccdm94 | upstream does not consider this a security issue, as per their binutils/SECURITY.txt security file. That is because this issue affects nm, an inspection tool. For bionic and earlier, the patch seems to introduce a memory leak, so these releases will be marked as ignored. |
