DConnect Daemon listen_thread_udp() buffer overflow
| dconnect-daemon-listenthreadudp-bo (28276) |  High Risk |
Description:
DConnect Daemon is vulnerable to a buffer overflow, caused by improper bounds checking by the listen_thread_udp() function in main.c. By sending a long nickname of more than 32 characters, a remote attacker could overflow a buffer and execute arbitrary code on the system.
Note: By default, the UDP port is not enabled and the min_slots parameter in dcd.conf must be enabled for this vulnerability to be exploitable.
