  arbitrary code as root if sudo was configured to allow the attacker to use
  sudoedit. The sudoedit pseudo-command is not used in the default
  installation of Ubuntu. (CVE-2010-0426)

  It was discovered that sudo did not reset group permissions when the
  'runas_default' configuration option was used. A local attacker could
  exploit this to escalate group privileges if sudo was configured to allow
  the attacker to run commands under the runas_default account. The
  runas_default configuration option is not used in the default installation
  of Ubuntu. This issue affected Ubuntu 8.04 LTS, 8.10 and 9.04.
