"With the previous upload of the isc-dhcp package to Debian Squeeze LTS
two issues got introduced into LTS that are resolved by this upload.

(1)

CVE-2015-8605 had only been resolved for the LDAP variant of the DHCP
server package built from the isc-dhcp source package. With upload of
version 4.1.1-P1-15+squeeze10, now all DHCP server variants (LDAP and
non-LDAP alike) include the fix for CVE-2015-8605. Thanks to Ben
Hutchings for spotting this inaccuracy.

(2)

The amd64 binary build of the previously uploaded isc-dhcp version
(4.1.1-P1-15+squeeze9) was flawed and searched for the dhcpd.conf
configuration file at the wrong location [1,2,3]. This flaw in the
amd64 build had been caused by a not-100%-pure-squeeze-lts build
system on the maintainer's end. The amd64 build of version
4.1.1-P1-15+squeeze10 has been redone in a brand-new build environment
and does not show the reported symptom(s) anymore.

I deeply apologize for the experienced inconvenience to all who
encountered this issue.
