{"id":"UBUNTU-CVE-2016-6830","details":"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).","modified":"2026-04-22T10:55:08.277365Z","published":"2017-01-10T15:59:00Z","upstream":["CVE-2016-6830"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-6830"},{"type":"REPORT","url":"http://lists.nongnu.org/archive/html/chicken-announce/2016-08/msg00001.html"},{"type":"REPORT","url":"http://www.openwall.com/lists/oss-security/2016/08/18/2"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2016-6830"}],"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_version":"4.9.0.1-1","binary_name":"chicken-bin"},{"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-2016-6830.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:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
