chicken: Unsafe pointer dereference due to incorrect pair? check in Scheme "length" procedure (CVE-2017-9334)
An incorrect "pair?" check in the Scheme "length" procedure results in an unsafe pointer dereference in all CHICKEN Scheme versions prior to 4.13,
which allows an attacker to cause a denial of service by passing an improper list to an application that calls "length" on it.
