Alpine: multiple chicken packages: security update to 4.11.0-r2 (deprecated)

critical Tenable Cloud Security Plugin ID 400944

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- 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)

- 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). (CVE-2016-6831)
