CVE-2012-2248: isc-dhcp, Debian-specific: build path included in PATH

Michael Stapelberg, Tollef Fog Heen, and Michael Biebl discovered that
dhclient was setting dhclient-script's PATH to one that included a
subdirectory of the build directory.
This issue is caused by the way isc-dhcp is packaged in Debian.
At least two versions of isc-dhcp for the amd64 (x86_64) architecture in
Debian were found two be setting PATH to a subdirectory of /home/zero79/,
which would allow a user with such HOME directory to be able to execute code
To clarify the bug report: it is not specific to samba or hooks in general,
PATH is injected in the environment passed to the execve() call that
Since this issue doesn't affect the stable release, there won't be a DSA.
This email is just a heads up.
