[kamailio/kamailio] Kamailio crashes with debug level > 2 and registering from certain SIP clients (#1403)

by mechanixza

### Description  When registering a soft client running on my Android phone (Grandstream Wave), Kamailio crashes every time when the client registers. When setting the debug level below 3 Kamailio does not crash. I have only found the problem with this SIP client. Others are working fine. ### Troubleshooting #### Reproduction  Set debug level greather than 2 and register the Grandstream Wave soft client from an Android phone. Kamailio then crashes. #### Log Messages  just before crashing I get the following message: 0(7819) ERROR: <core> [core/udp_server.c:484]: udp_rcv_loop(): print buffer building failed (10/16/4) ### Possible Solutions  The problem seems to come from non-printable characters sent by the SIP client causing Kamailio to crash. Changing line 482 in udp_server.c from l = snprintf(printbuf+j, 6, " %02X ", buf[i]); to l = snprintf(printbuf+j, 6, " %02X ", (unsigned char)buf[i]); fixes the problem. The compiler treats buf[i] as a signed integer and prepends 'FFFFFF' to the string making it longer than 6 characters. Casting buf[i] as an unsigned char prevents Kamailio from crashing. ### Additional Information * **Kamailio Version** - output of `kamailio -v` version: kamailio 5.1.0 (x86_64/linux) flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB poll method support: poll, epoll_lt, epoll_et, sigio_rt, select. id: unknown compiled with gcc 5.3.1 * **Operating System**:  Ubuntu 16.04 (Xenial) -- You are receiving this because you are subscribed to this thread.
