[OE-core] bash: Fix CVE-2019-18276

[Yu, Mingli]

Hi Anuj,

I agree the Backport status is not accurate as the patch doesn't go to master branch, but why do you say the patch is irrelevant to the CVE-2019-18276, could you help to provide more info?

Hi Chet,
Does https://git.savannah.gnu.org/cgit/bash.git/commit/?h=devel&id=951bdaad7a18cc0dc1036bba86b18b90874d39ff fix the issue reported in CVE-2019-18276? Could you help to provide some info here?

Thanks,
Mingli

There are other issues with this patch which should also be fixed I
think. It has been marked as a Backport while it is not one. The patch
includes changes that are irrelevant to the CVE. And, it should have
gone to master first.


Thanks,
