NVD Description

Note: Versions mentioned in the description apply only to the upstream isc-dhcp package and not the isc-dhcp package as distributed by Debian. See How to fix? for Debian:9 relevant fixed versions and status.

A vulnerability stemming from failure to properly clean up closed OMAPI connections can lead to exhaustion of the pool of socket descriptors available to the DHCP server. Affects ISC DHCP 4.1.0 to 4.1-ESV-R15, 4.2.0 to 4.2.8, 4.3.0 to 4.3.6. Older versions may also be affected but are well beyond their end-of-life (EOL). Releases prior to 4.1.0 have not been tested.
