| शीर्षक | D-Link DIR605 B1v202WWB03 B1v202WWB03 Out-of-bounds Write |
|---|
| विवरण | An out-of-bounds write vulnerability exists in the L2TP control message parser of D-Link DIR-605. When the device is configured to use L2TP WAN connectivity, a malicious L2TP server or an attacker able to spoof or intercept the L2TP peer can send a crafted control packet containing an oversized Host Name AVP and trigger memory corruption in the tunnel setup logic.
The vulnerability is caused by an off-by-one write when the code copies a length-delimited Host Name AVP into a fixed-size `peer_hostname` buffer and then places the terminating NUL byte at `len + 1` instead of `len`. |
