Synopsis

The remote Debian host is missing a security update.

Description

Jon Franklin and Pawel Wieczorkiewicz found an issue in the ISC DHCP client and server when parsing lease information, which could lead to denial of service via application crash.

For Debian 9 stretch, this problem has been fixed in version 4.3.5-3+deb9u2.

We recommend that you upgrade your isc-dhcp packages.

For the detailed security status of isc-dhcp please refer to its security tracker page at:

Solution

Upgrade the affected packages.
