+From dedad73e5e7a75d01a5f3d5a6702ab8ccd2ff40d Mon Sep 17 00:00:00 2001
+From: mancha <mancha1@hush.com>
+Date: Thu, 11 Jul 2013 10:08:07 +0100
+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).
+
+When using glibc's crypt(), check return value to avoid a possible
+NULL pointer dereference.
+
+Patch by mancha1@hush.com.
