affected Ubuntu 8.04 LTS, 8.10, 9.04 and 9.10. (CVE-2009-3553,
CVE-2010-0302)

Ronald Volgers discovered that the CUPS lppasswd tool could be made to load
localized message strings from arbitrary files by setting an environment
variable. A local attacker could exploit this with a format-string
vulnerability leading to a root privilege escalation. The default compiler
options for Ubuntu 8.10, 9.04 and 9.10 should reduce this vulnerability to
a denial of service. (CVE-2010-0393)");
