Due to an incomplete fix for CVE-2012-6125, all versions of CHICKEN Scheme up to and including 4.12.0 are vulnerable to an algorithmic complexity attack. An attacker can provide crafted input which, when inserted into the symbol table, will result in O(n) lookup time. Debido a una solución incompleta para el CVE-2012-6125, todas las versiones de CHICKEN Scheme hasta 4.12.0 incluyéndola, son vulnerables a un ataque de complejidad algorítmica. Un atacante puede proporcionar una entrada creada que, cuando sea insertada en la tabla de símbolos, resultará en un tiempo de búsqueda O(n). • http://lists.gnu.org/archive/html/chicken-announce/2017-07/msg00000.html • CWE-407: Inefficient Algorithmic Complexity •

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. Un chequeo de "pair" incorrecto en el procedimiento "lenght" de Scheme resulta en una desreferencia de puntero insegura en todas las versiones de CHICKEN Scheme anteriores a 4.13, lo que permite a un atacante causar una denegación de servicio pasando una lista incorrecta a una aplicación que llama a "length". • http://lists.nongnu.org/archive/html/chicken-announce/2017-05/msg00000.html http://lists.nongnu.org/archive/html/chicken-hackers/2017-05/msg00099.html • CWE-20: Improper Input Validation •
