Vulnerability Note VU#686084
ISC DHCP server DHCPv6 decline message processing vulnerability
ISC DHCPv6 versions 4.0.x - 4.2.x are susceptible to a denial-of-service vulnerability.
The ISC Advisory states:
"When the DHCPv6 server code processes a message for an address that was previously declined and internally tagged as abandoned it can trigger an assert failure resulting in the server crashing. This could be used to crash DHCPv6 servers remotely. This issue only affects DHCPv6 servers. DHCPv4 servers are unaffected."
A remote attacker may cause a denial of service.
