Description Tim Sammut (RETIRED) gentoo-dev 2011-07-04 05:46:47 UTC
From the Red Hat bug at $URL:

It has been found that calling VirDomainGetVcpus with bogus parameters can lead
to integer overflow and subsequent heap corruption. A remote attacker could use
this flaw to crash libvirtd (DoS).

Great, thanks. Going with 0.9.3-r1 since 0.9.3 has been removed.

Please fix a minor issue at bug 379853. Is a regression for me.

CVE-2011-2511 (
  Integer overflow in libvirt before 0.9.3 allows remote authenticated users
  to cause a denial of service (libvirtd crash) and possibly execute arbitrary
  code via a crafted VirDomainGetVcpus RPC call that triggers memory
