CVE-2016-6830

CRITICAL

CHICKEN Scheme <= 4.11.0 - Buffer Overflow via process-execute and process-spawn

Title source: llm
STIX 2.1

Description

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).
