+Subject: Handle NULL returns from glibc 2.17+ crypt().
+
+Starting with glibc 2.17 (eglibc 2.17), crypt() fails with EINVAL
+(w/ NULL return) if the salt violates specifications. Additionally,
+on FIPS-140 enabled Linux systems, DES/MD5-encrypted passwords
+passed to crypt() fail with EPERM (w/ NULL return).
+
+If using glibc's crypt(), check return value to avoid a possible
+NULL pointer dereference.
