[ubuntu/quantal] isc-dhcp 4.2.4-1ubuntu7 (Accepted)

isc-dhcp (4.2.4-1ubuntu7) quantal-proposed; urgency=low

  * debian/dhclient-script.linux: Explicitly set the PATH to that of
    ENV_SUPATH in /etc/login.defs and unset various other variables. We need
    to do this so /sbin/dhclient cannot abuse the environment to escape
    AppArmor confinement via this script. This can be removed once AppArmor
    supports environment filtering (LP: 1045985). Don't worry about
    debian/dhclient-script.linux.udeb or debian/dhclient-script.kfreebsd*
    since AppArmor isn't used in these environments.
