Notes
Author | Note |

mdeslaur | In Ubuntu, the build directory is set to PATH=/build/buildd/isc-dhcp-4.2.4/debian/tmp/usr/sbin. since it is a top-level directory, the attacker would need to be root to exploit this. Also, USN-1571-1 sets an explicit PATH in dhclient-script, so it's likely we're not vulnerable at all. |
