FINAL RESULTS:
data/posh-0.14.1/path.c:251:28: [5] (buffer) gets:
Does not check for buffer overflows (CWE-120, CWE-20). Use fgets() instead.
printf("enter CDPATH: "); gets(cdpath);
data/posh-0.14.1/path.c:252:25: [5] (buffer) gets:

data/posh-0.14.1/proto.h:273:12: [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.
extern int readlink (const char *path, char *buf, int bufsize);
data/posh-0.14.1/conf-end.h:40:37: [4] (shell) system:
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.

(CWE-134). Use a constant for the format specification.
extern int fprintf (FILE *fp, const char *fmt, ...);
data/posh-0.14.1/sh.h:258:29: [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.
