16 Jul 2017 — 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 ... • http://lists.gnu.org/archive/html/chicken-announce/2017-07/msg00000.html • CWE-407: Inefficient Algorithmic Complexity •

01 Jun 2017 — 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 serv... • http://lists.nongnu.org/archive/html/chicken-announce/2017-05/msg00000.html • CWE-20: Improper Input Validation •

16 Mar 2017 — An issue was discovered in CHICKEN Scheme through 4.12.0. When using a nonstandard CHICKEN-specific extension to allocate an SRFI-4 vector in unmanaged memory, the vector size would be used in unsanitised form as an argument to malloc(). With an unexpected size, the impact may have been a segfault or buffer overflow. Se ha descubierto un problema en CHICKEN Scheme hasta la versión 4.12.0. Cuando se utiliza una extensión CHICKEN-specific no estándar para ubicar un vector SRFI-4 en memoria no administrada, el... • http://lists.gnu.org/archive/html/chicken-announce/2017-03/msg00000.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •
