Hi Stable release managers,

This brings the update to address CVE-2021-25217 / #989157 in buster
(the fix was applied already as NMU in unstable and unblocked
accordingly).

The debian/changelog entry is

+isc-dhcp (4.4.1-2+deb10u1) buster; urgency=medium
+
+  * Non-maintainer upload.
+  * A buffer overrun in lease file parsing code can be used to exploit a
+    common vulnerability shared by dhcpd and dhclient (CVE-2021-25217)
+    (Closes: #989157)
+

The debdiff attached accordingly. But it needs a d-i ack as well from
Cyril as it produces udebs.

Regards,
Salvatore
