{"id":"UBUNTU-CVE-2016-6831","details":"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).","modified":"2026-04-22T10:54:46.227412Z","published":"2017-01-10T15:59:00Z","upstream":["CVE-2016-6831"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-6831"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2016/08/18/2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2016-6831"}],"affected":[{"package":{"name":"chicken","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/chicken@4.9.0.1-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.9.0.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"chicken-bin","binary_version":"4.9.0.1-1"},{"binary_name":"libchicken7","binary_version":"4.9.0.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2016/UBUNTU-CVE-2016-6831.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"low"}]}
