FINAL RESULTS:
data/guvcview-2.0.6+debian/guvcview/core_io.c:81:3: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]
(CWE-120). Consider using snprintf, strcpy_s, or strlcpy (warning: strncpy
easily misused).
strcpy(src, tmp);
data/guvcview-2.0.6+debian/guvcview/core_io.c:420:5: [4] (buffer) sscanf:
The scanf() family's %s operation, without a limit specification, permits
buffer overflows (CWE-120, CWE-20). Specify a limit to %s, or use a
different input function. If the scanf format is influenceable by an
attacker, it's exploitable.

Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(new_name, "%s-%llu.%s", noextname, suffix, extension);

vsnprintf.
sprintf(new_name, "%s-%llu", filename, suffix);
data/guvcview-2.0.6+debian/gview_audio/audio_portaudio.c:232:6: [4] (format) printf:
