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 •

10 Jan 2017 — The "process-execute" and "process-spawn" procedures in CHICKEN Scheme used fixed-size buffers for holding the arguments and environment variables to use in its execve() call. This would allow user-supplied argument/environment variable lists to trigger a buffer overrun. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released). Los procedimientos "process-execute" y "process-spawn" en CHICKEN Scheme utilizaron búfers de tamaño fijo para man... • http://lists.nongnu.org/archive/html/chicken-announce/2016-08/msg00001.html • CWE-119: Improper Restriction of Operations within the Bounds of a Memory Buffer •

10 Jan 2017 — The "process-execute" and "process-spawn" procedures did not free memory correctly when the execve() call failed, resulting in a memory leak. This could be abused by an attacker to cause resource exhaustion or a denial of service. This affects all releases of CHICKEN up to and including 4.11 (it will be fixed in 4.12 and 5.0, which are not yet released).

10 Jan 2017 — The "spiffy-cgi-handlers" egg would convert a nonexistent "Proxy" header to the HTTP_PROXY environment variable, which would allow attackers to direct CGI programs which use this environment variable to use an attacker-specified HTTP proxy server (also known as a "httpoxy" attack).

10 Jan 2017 — The "http-client" egg always used a HTTP_PROXY environment variable to determine whether HTTP traffic should be routed via a proxy, even when running as a CGI process. Under several web servers this would mean a user-supplied "Proxy" header could allow an attacker to direct all HTTP requests through a proxy (also known as a "httpoxy" attack). This affects all versions of http-client before 0.10.
