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.

Exploit prediction (EPSS)

73.62% probability of exploitation in the next 30 days, higher than 99% of all scored CVEs.
