| Título | D-Link DIR-825 C1_FW3.00b32 C1_FW3.00b32 Out-of-bounds Write |
|---|
| Descrição | An out-of-bounds write vulnerability exists in the `rp-l2tp` component of D-Link DIR-825. When the device is configured to use L2TP WAN connectivity, a malicious L2TP server or an attacker able to spoof or intercept the remote peer can send a crafted control message containing a large Host Name AVP and trigger memory corruption during tunnel setup.
The issue is caused by off-by-one termination logic after copying a length-delimited Host Name AVP into a fixed-size `peer_hostname` buffer. |
