Comment 5 Todd Cullum 2020-12-22 20:12:24 UTC

binutils as shipped in Red Hat Developer Toolsets 9 and 10, Red Hat Enterprise Linux 8 BaseOS and GCC Toolsets 9 and 10, are all not affected by this flaw as it was introduced in a newer version of binutils code than shipped for BaseOS and the 9 toolsets, and already patched in the versions shipped with 10 toolsets.
