ISC DHCP < 2.0pl5 - Denial of Service via DHCPDISCOVER Packet with 32 Byte Client-Identifier

Title source: llm
STIX 2.1

Description

The supersede_lease function in memory.c in ISC DHCP (dhcpd) server 2.0pl5 allows remote attackers to cause a denial of service (application crash) via a DHCPDISCOVER packet with a 32 byte client-identifier, which causes the packet to be interpreted as a corrupt uid and causes the server to exit with "corrupt lease uid."
