Notes

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.
