Ubuntu 10.04 LTS / 10.10 / 11.04 : libvirt vulnerability (USN-1180-1)

Medium Nessus Plugin ID 55730


The remote Ubuntu host is missing a security-related patch.


Eric Blake discovered an integer overflow flaw in libvirt. A remote authenticated attacker could exploit this by sending a crafted VCPU RPC call and cause a denial of service via application crash.

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.


Update the affected libvirt-bin package.
