Debian DLA-1313-1 : isc-dhcp security update
Medium Nessus Plugin ID 108569
SynopsisThe remote Debian host is missing a security update.
DescriptionSeveral vulnerabilities have been discovered in the ISC DHCP client, relay and server. The Common Vulnerabilities and Exposures project identifies the following issues :
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.
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.
