Subject: [Qemu-devel] [PATCH] coverity-model: replay data is considered trusted
Date: Mon, 14 May 2018 16:12:18 +0200 [thread overview]
Message-ID: <20180514141218.28438-1-pbonzini@redhat.com> (raw)
Replay data is not considered a possible attack vector; add a model that
does not use getc so that "tainted data" warnings are suppressed.
