Package : isc-dhcp
CVE ID : CVE-2017-3144 CVE-2018-5732 CVE-2018-5733
Debian Bug : 887413 891785 891786

Several vulnerabilities have been discovered in the ISC DHCP client,
relay and server. The Common Vulnerabilities and Exposures project
identifies the following issues:

CVE-2017-3144

It was discovered that the DHCP server does not properly clean up
closed OMAPI connections, which can lead to exhaustion of the pool
of socket descriptors available to the DHCP server, resulting in
denial of service.

CVE-2018-5732

Felix Wilhelm of the Google Security Team discovered that the DHCP
client is prone to an out-of-bound memory access vulnerability when
processing specially constructed DHCP options responses, resulting
in potential execution of arbitrary code by a malicious DHCP server.

CVE-2018-5733

Felix Wilhelm of the Google Security Team discovered that the DHCP
server does not properly handle reference counting when processing
client requests. A malicious client can take advantage of this flaw
to cause a denial of service (dhcpd crash) by sending large amounts
of traffic.

For the oldstable distribution (jessie), these problems have been fixed
in version 4.3.1-6+deb8u3.

For the stable distribution (stretch), these problems have been fixed in
version 4.3.5-3+deb9u1.

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:
