FINAL RESULTS:
data/nss-wrapper-1.1.11/src/nss_wrapper.c:293:2: [4] (format) vsnprintf:
If format strings can be influenced by an attacker, they can be exploited,
and note that sprintf variations do not always \0-terminate (CWE-134). Use
a constant for the format specification.
vsnprintf(buffer, sizeof(buffer), format, va);
data/nss-wrapper-1.1.11/tests/test_getaddrinfo.c:128:7: [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.
rc = system(touch_cmd);
data/nss-wrapper-1.1.11/tests/test_shadow.c:46:23: [4] (crypto) crypt:
The crypt functions use a poor one-way hashing algorithm; since they only
accept passwords of 8 characters or fewer and only a two-byte salt, they
are excessively vulnerable to dictionary attacks given today's faster
computing equipment (CWE-327). Use a different algorithm, such as SHA-256,
with a larger, non-repeating salt.
encrypted_password = crypt("secret", sp->sp_pwdp);
