[Bug 1045986] Re: Ubuntu AppArmor policy is too lenient with shell scripts

[Launchpad Bug Tracker]

This bug was fixed in the package dhcp3 - 3.1.3-2ubuntu3.4

---------------
dhcp3 (3.1.3-2ubuntu3.4) lucid-security; 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. Don't worry about
    debian/dhclient-script.udeb or debian/dhclient-script.kfreebsd since
    AppArmor isn't used in these environments.
    - LP: #1045986
  * debian/patches/adjust-configure-for-linux3.dpatch: default to linux-2.2
    for 3.0+ kernels
