FINAL RESULTS:
data/lwt-5.3.0/src/unix/unix_c/unix_chmod_job.c:57:17: [5] (race) chmod:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchmod( ) instead.
job->result = chmod(job->path, job->mode);
data/lwt-5.3.0/src/unix/unix_c/unix_chown_job.c:59:17: [5] (race) chown:
This accepts filename arguments; if an attacker can move those files, a
race condition results. (CWE-362). Use fchown( ) instead.
job->result = chown(job->path, job->ower, job->group);
data/lwt-5.3.0/src/unix/unix_c/unix_readlink_job.c:33:23: [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.
link_length = readlink(job->name, job->buffer, buffer_size);
data/lwt-5.3.0/src/unix/unix_c/unix_readlink_job.c:63:35: [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.
LWT_UNIX_INIT_JOB_STRING(job, readlink, 0, name);
data/lwt-5.3.0/src/unix/unix_c/unix_access_job.c:84:17: [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.
job->result = access(job->path, job->mode);
data/lwt-5.3.0/src/unix/unix_c/unix_getlogin_job.c:45:28: [4] (misc) getlogin:
It's often easy to fool getlogin. Sometimes it does not work at all,
because some program messed up the utmp file. Often, it gives only the
first 8 characters of the login name. The user currently logged in on the
controlling tty of our program need not be the user who started it. Avoid
getlogin() for security-related purposes (CWE-807). Use getpwuid(geteuid())
and extract the desired information instead.
LWT_UNIX_INIT_JOB(job, getlogin, 0);
data/lwt-5.3.0/src/unix/windows_c/windows_system_job.c:54:32: [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.
LWT_UNIX_INIT_JOB(job, system, 0);
data/lwt-5.3.0/src/unix/lwt_unix_stubs.c:245:3: [3] (misc) InitializeCriticalSection:
Exceptions can be thrown in low-memory situations. Use
InitializeCriticalSectionAndSpinCount instead.
InitializeCriticalSection(mutex);
data/lwt-5.3.0/src/unix/lwt_unix_stubs.c:252:51: [3] (misc) EnterCriticalSection:
On some versions of Windows, exceptions can be thrown in low-memory

void lwt_unix_mutex_lock(lwt_unix_mutex *mutex) { EnterCriticalSection(mutex); }
data/lwt-5.3.0/src/unix/lwt_unix_stubs.c:269:3: [3] (misc) InitializeCriticalSection:

situations. Use InitializeCriticalSectionAndSpinCount instead.
EnterCriticalSection(mutex);
data/lwt-5.3.0/src/unix/unix_c/unix_chroot_job.c:55:17: [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.
job->result = chroot(job->path);
data/lwt-5.3.0/src/unix/windows_c/windows_system_job.c:49:10: [3] (shell) CreateProcess:
This causes a new process to execute and is difficult to use safely
(CWE-78). Specify the application path in the first argument, NOT as part
of the second, or embedded spaces could allow an attacker to force a
different program to run.
if (!CreateProcess(NULL, String_val(cmdline), NULL, NULL, TRUE, 0, NULL,
