FINAL RESULTS:
data/fuzz-0.6/fuzz.c:350:7: [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(progname,"/",MAXPATH);
data/fuzz-0.6/fuzz.c:351:7: [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(progname,argv[optind],MAXPATH);
data/fuzz-0.6/fuzz.c:1116:5: [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.
if(readlink(cur,tmpbuf,MAXPATH-1)==-1){
data/fuzz-0.6/fuzz.c:360:5: [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(progname,argv[optind]);
data/fuzz-0.6/fuzz.c:815:3: [4] (shell) execv:
This causes a new program to execute and is difficult to use safely
(CWE-78). try using a library call that implements the same functionality
if available.
execv(progname,arguments);
data/fuzz-0.6/fuzz.c:998:2: [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(distribution+1,tmpbuf+5);
data/fuzz-0.6/fuzz.c:1000:5: [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.

data/fuzz-0.6/fuzz.c:312:8: [3] (misc) chroot:
chroot can be very helpful, but is hard to use correctly (CWE-250, CWE-22).
Make sure the program immediately chdir("/"), closes file descriptors, and
drops root privileges, and that all necessary files (and no more!) are in
the new root.
