Subject: [PATCH-for-6.2 v3 0/2] hw/block/fdc: Fix CVE-2021-20196
Date: Thu, 18 Nov 2021 13:06:33 +0100 [thread overview]
Message-ID: <20211118120635.4043197-1-philmd@redhat.com> (raw)
I'm not sure what happened to v1 from Prasad, so since we are
at rc2 I took a simpler approach to fix this CVE: create an
empty drive to satisfy the BlockBackend API calls.
Added Alexander's reproducer along.
Since v2:
- Reword comment (Darren)
- Add Darren R-b tag
v2: https://lore.kernel.org/qemu-devel/20211117232422.1026411-1-philmd@redhat.com/
v1: https://lore.kernel.org/qemu-devel/20210123100345.642933-1-ppandit@redhat.com/
Based-on: <20211118115733.4038610-1-philmd@redhat.com>
