FINAL RESULTS:
data/nbdkit-1.22.3/plugins/sh/sh.c:123:7: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.

If format strings can be influenced by an attacker, they can be exploited
(CWE-134). Use a constant for the format specification.
vfprintf (stderr, fs, args);

fprintf (stderr, \
data/nbdkit-1.22.3/filters/error/error.c:278:9: [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.

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 (io->name, name);
data/nbdkit-1.22.3/filters/extentlist/extentlist.c:176:14: [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.
