Red Hat Product Errata RHSA-2009:0382 0 normal SHIPPED_LIVE Moderate: libvirt security update 2009-03-19 16:10:09 UTC

Description Josh Bressers 2009-02-10 20:10:07 UTC 
A buffer overflow flaw was found in libvirt_proxy. libvirt_proxy is set to
run as a setuid root by default, so in theory this could allow for a local
user to become root.

Normally the stack protector would prevent this from being an issue, but it
seems that with gcc optimizations, the function in question is being
inlined into main(), preventing the stack protector from catching this.

The original report can be found here:
