NVD Description

Note: Versions mentioned in the description apply only to the upstream dhcp-client package and not the dhcp-client package as distributed by RHEL.

In ISC DHCP 1.0 -> 4.4.3, ISC DHCP 4.1-ESV-R1 -> 4.1-ESV-R16-P1 a system with access to a DHCP server, sending DHCP packets crafted to include fqdn labels longer than 63 bytes, could eventually cause the server to run out of memory.
