+Subject: [PATCH] Fixed reporting an error when failed to build the mountpoint
+
+The size check was inefficient because getcwd() uses an unsigned int
+argument.
+
+Fixes CVE-2019-9755: An integer underflow issue exists in ntfs-3g 2017.3.23.
+A local attacker could potentially exploit this by running /bin/ntfs-3g with
+specially crafted arguments from a specially crafted directory to cause a
+heap buffer overflow, resulting in a crash or the ability to execute
+arbitrary code.  In installations where /bin/ntfs-3g is a setuid-root
+binary, this could lead to a local escalation of privileges.
