FINAL RESULTS:
data/libdvdread-6.1.1/msvc/msvc/include/unistd.h:67:9: [5] (race) readlink:
This accepts filename arguments; if an attacker can move those files or
change the link content, a race condition results. Also, it does not
terminate with ASCII NUL. (CWE-362, CWE-20). Reconsider approach.
#define readlink
data/libdvdread-6.1.1/src/dvd_udf.c:866:3: [5] (buffer) strncat:
Easily used incorrectly (e.g., incorrectly computing the correct maximum
size to add) [MS-banned] (CWE-120). Consider strcat_s, strlcat, snprintf,
or automatically resizing strings. Risk is high; the length parameter
appears to be a constant, instead of computing the number of characters
left.
strncat(tokenline, filename, MAX_UDF_FILE_NAME_LEN - 1);
data/libdvdread-6.1.1/msvc/msvc/contrib/dirent/dirent.c:52:13: [4] (buffer) strcat:

easily misused).
strcat(strcpy(dir->name, name), all);
data/libdvdread-6.1.1/msvc/msvc/include/os_types.h:15:9: [4] (format) snprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
#define snprintf _snprintf
data/libdvdread-6.1.1/msvc/msvc/include/os_types.h:15:18: [4] (format) _snprintf:

a constant for the format specification.

easily misused).
strcpy( new_path, path );
data/libdvdread-6.1.1/src/dvd_reader.c:296:3: [4] (buffer) strcat:
