Debian 9 Stretch DLA-2304-1 Moderate: Libpam-radius-auth Buffer Overflow

`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.
