CVE-2016-6831 Information

Description

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).
