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.

Security readout for executives and security teams

CVE-2017-9334 is a denial-of-service flaw in CHICKEN Scheme before 4.13. A crafted improper list can trigger an unsafe pointer dereference when an application calls the Scheme length procedure, potentially crashing the affected application. Exposure is likely limited to systems running CHICKEN Scheme before 4.13, especially applications that process untrusted Scheme data structures or external input that can become lists. The source bundle does not identify specific downstream products. Prioritize remediation where CHICKEN Scheme handles untrusted input or supports internet-facing services. Otherwise, handle as legacy dependency cleanup with moderate urgency. Mitigation focus: Inventory CHICKEN Scheme runtimes and embedded copies in applications.; Upgrade affected CHICKEN Scheme deployments to version 4.13 or later where supported.; Review applications that call length on data derived from users or external systems..
