GHSA-CQ4F-M4R6-7827

Vulnerability from github – Published: 2022-11-14 19:00 – Updated: 2022-11-18 00:30

Details

There is a vulnerability in DHCPv6 packet parsing code that could be explored by remote attacker to craft a packet that could cause buffer overflow in a memcpy call, leading to out-of-bounds memory write that would cause dhcp6relay to crash. Dhcp6relay is a critical process and could cause dhcp relay docker to shutdown. Discovered by Eugene Lim of GovTech Singapore.

Severity ?

7.5 (High)
