CVE-2012-4423: Null Pointer Dereference

First published: Thu Sep 13 2012(Updated: )

It has been found that sending RPC message with an event as the RPC number, or RPC number that falls into gap in the RPC dispatch table, can lead to libvirtd accessing memory at page zero. A remote attacker could use this flaw to crash libvirtd (DoS). Proposed upstream fix: <a href="https://www.redhat.com/archives/libvir-list/2012-September/msg00843.html">https://www.redhat.com/archives/libvir-list/2012-September/msg00843.html</a>
