CVE-2010-2242 low priority: Ubuntu including 1 source packages (libvirt), 7 status rows across 7 suites (dapper, hardy, jaunty, karmic, lucid, maverick, upstream): released 6, DNE 1.
Red Hat libvirt 0.2.0 through 0.8.2 creates iptables rules with improper mappings of privileged source ports, which allows guest OS users to bypass intended access restrictions by leveraging IP address and source-port values, as demonstrated by copying and deleting an NFS directory tree.
