"The remote Debian host is missing a security update.");
  script_set_attribute(attribute:"description", value:
"`add_password` in pam_radius_auth.c in pam_radius 1.4.0 does not
correctly check the length of the input password, and is vulnerable to
a stack-based buffer overflow during memcpy(). An attacker could send
a crafted password to an application (loading the pam_radius library)
and crash it. Arbitrary code execution might be possible, depending on
the application, C library, compiler, and other factors.

For Debian 9 stretch, this problem has been fixed in version
1.3.16-5+deb9u1.

We recommend that you upgrade your libpam-radius-auth packages.
