Description The issue is related to the improper handling of data by the jdhcpd daemon in the Junos operating system. This can be exploited by a remote attacker using a specially crafted DHCPv6 packet, leading to the crash and restart of the jdhcpd daemon. Repeated crashes may cause an extended denial of service condition for subscribers attempting to obtain IPv6 addresses.
