CVE-2016-6831

HIGH

CHICKEN < 4.11.0 - Denial of Service via Memory Leak in process-execute and process-spawn

Title source: llm
STIX 2.1

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).
