Dan Carpenter b7a314054e isdn: icn: buffer overflow in icn_command() ... This buffer over was detected using static analysis: drivers/isdn/icn/icn.c:1325 icn_command() error: format string overflow. buf_size: 60 length: 98 The calculation for the length of the string is off because it assumes that the dial[] buffer holds a 50 character string, but actually it is at most 31 characters and NUL. I have removed the dial[] buffer because it isn't needed. The maximum length of the string is actually 79 characters and a NUL. I have made the cbuf[] array large enough to hold it and changed the sprintf() to an snprintf() as a further safety enhancement.
