FINAL RESULTS:
data/zzuf-0.15/src/libzzuf/network.c:171:13: [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(buf, parser);
data/zzuf-0.15/src/libzzuf/sys.c:82:21: [4] (format) fprintf:
If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
if (dladdr(&fprintf, &di) != 0)
data/zzuf-0.15/src/myfork.c:199:5: [4] (buffer) sprintf:
Does not check for buffer overflows (CWE-120). Use sprintf_s, snprintf, or
vsnprintf.
sprintf(str, "%s=%s", name, value);
data/zzuf-0.15/src/myfork.c:300:5: [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(libpath, opts->oldargv[0]);
data/zzuf-0.15/src/myfork.c:308:9: [4] (buffer) strcpy:
Does not check for buffer overflows when copying to destination [MS-banned]

easily misused).
strcpy(tmp + 1, LT_OBJDIR SONAME);
data/zzuf-0.15/src/myfork.c:309:13: [4] (race) access:
This usually indicates a security flaw. If an attacker can change anything
along the path between the call to access() and the file's actual use
(e.g., by moving files), the attacker can exploit the race condition
(CWE-362/CWE-367!). Set up the correct permissions (e.g., using setuid())
and try to open the file directly.

data/zzuf-0.15/src/myfork.c:310:13: [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).

vsnprintf.
sprintf(bigbuf, "%s:%s", tmp, libpath);
data/zzuf-0.15/src/myfork.c:333:9: [4] (shell) execvp:
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.

data/zzuf-0.15/src/myfork.c:362:9: [4] (buffer) strcpy:

a constant for the format specification.

(CWE-134). Use a constant for the format specification.
printf(MOREINFO, argv[0]);
data/zzuf-0.15/src/zzat.c:368:23: [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.

Statically-sized arrays can be improperly restricted, leading to potential
