the following problems :

  - CVE-2009-1300
    In time zones where daylight savings time occurs at
    midnight, the apt cron.daily script fails, stopping new
    security updates from being applied automatically.

  - CVE-2009-1358
    A repository that has been signed with an expired or
    revoked OpenPGP key would still be considered valid by
    APT."
