Package        : isc-dhcp
Version        : 4.2.2.dfsg.1-5+deb70u9
CVE ID         : CVE-2018-5732 CVE-2018-5733


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

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 Debian 7 "Wheezy", these problems have been fixed in version
4.2.2.dfsg.1-5+deb70u9.

We recommend that you upgrade your isc-dhcp packages.
