Description Philipp Hahn univentionstaff 2018-03-08 13:53:16 CET
New Debian isc-dhcp 4.3.1-6+deb8u3A~ fixes:
This update addresses the following issues:
 * Plugs a socket descriptor leak in OMAPI (CVE-2017-3144)
 * Corrected refcnt loss in option parsing (CVE-2018-5733)
 * Correct buffer overrun in pretty_print_option (CVE-2018-5732)

CVE-2017-3144 dhcp: omapi code doesn't free socket descriptors when empty message is received allowing denial-of-service
CVE-2018-5733 dhcp: Reference count overflow in dhcpd allows denial of service
CVE-2018-5732 dhcp: Buffer overflow in dhclient possibly allowing code execution triggered by malicious server
