FINAL RESULTS:
data/jdupes-1.19.0/jody_paths.c:101:3: [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(p1, src, PATHBUF_SIZE);
data/jdupes-1.19.0/jody_paths.c:102:3: [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

left.
strncat(p2, dest, PATHBUF_SIZE);
data/jdupes-1.19.0/act_linkfiles.c:164:13: [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/jdupes-1.19.0/act_linkfiles.c:212:9: [4] (buffer) strcpy:

data/jdupes-1.19.0/jdupes.c:994:3: [1] (buffer) strncpy:

data/jdupes-1.19.0/jdupes.c:998:3: [1] (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 low because the source is a
constant string.

Easily used incorrectly (e.g., incorrectly computing the correct maximum
