Details

marshall in dhcp_packet.c in simple-dhcp-server through ec976d2 allows remote attackers to cause a denial of service by sending a malicious DHCP packet. The crash is caused by a type confusion bug that results in a large memory allocation; when this memory allocation fails the DHCP server will crash.

Severity

6.5 (Medium)
