  with non-ASCII usernames. A remote attacker could use this flaw to cause a
  denial of service, or possibly obtain login access with a different users
  username. This issue only affected Ubuntu 8.04 LTS. (CVE-2009-0887)

  It was discovered that the PAM pam_xauth, pam_env and pam_mail modules
  incorrectly handled dropping privileges when performing operations. A local
  attacker could use this flaw to read certain arbitrary files, and access
  other sensitive information. (CVE-2010-3316, CVE-2010-3430, CVE-2010-3431,
  CVE-2010-3435)
  
  It was discovered that the PAM pam_namespace module incorrectly cleaned the
  environment during execution of the namespace.init script. A local attacker
  could use this flaw to possibly gain privileges. (CVE-2010-3853)
  
  It was discovered that the PAM pam_xauth module incorrectly handled certain
  failures. A local attacker could use this flaw to delete certain unintended
  files. (CVE-2010-4706)
  
  It was discovered that the PAM pam_xauth module incorrectly verified
  certain file properties. A local attacker could use this flaw to cause a
  denial of service. (CVE-2010-4707)";
