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).

CVE-2016-6830 CVE-2016-6831 chicken: Buffer overflow and a memory leak in the POSIX unit's procedures process-execute and process-spawn
A buffer overflow error was found in the POSIX unit's procedures
process-execute and process-spawn. The code allocated a buffer
of size ARG_MAX for the argument array, and ENV_MAX for the
environment array, then copied the strings from the input lists
into that buffer *without* checking the length of the lists.
On modern Linuxen, ARG_MAX and ENV_MAX are both undefined, which
exacerbated the problem: CHICKEN would fall back to 256 for ARG_MAX
and 1024 for ENV_MAX when these were undefined.
Additionally, a memory leak existed in this code, which would be
triggered when an error is raised during argument and environment
processing (e.g., if one of the argu
