| Title | D-Link Router FW120B05_decode Memory Corruption |
|---|
| Description | D-Link DIR-878 contains a stack-based buffer overflow in the SetDynamicDNSIPv6Settings handler. The handler copies the attacker-controlled value with IPv6Address and Hostname parameters into a fixed-size stack buffer using sprintf without validating its length. An oversized value causes stack memory corruption and reliably crashes the web management service. |
