CVE-2016-2774

MEDIUM

ISC DHCP 4.1.x < 4.1-ESV-R13 and 4.2.x-4.3.x < 4.3.4 - Denial of Service via Concurrent TCP Session Flood

Title source: llm
STIX 2.1

Description

ISC DHCP 4.1.x before 4.1-ESV-R13 and 4.2.x and 4.3.x before 4.3.4 does not restrict the number of concurrent TCP sessions, which allows remote attackers to cause a denial of service (INSIST assertion failure or request-processing outage) by establishing many sessions.
