The attacker can write \"ALL ALL=(ALL) NOPASSWD:ALL\" to /proc/#####/fd/3 at a time when Sudo is prompting for a password. NOTE: This has been disputed due to the way Linux /proc works. It has been argued that writing to /proc/#####/fd/3 would only be viable if you had permission to write to /etc/sudoers. Even with write permission to /proc/#####/fd/3, it would not help you write to /etc/sudoers","title":"CVE description"}],"product_status":{"known_not_affected":["SUSE CaaS Platform 3.0:sudo","SUSE Container as a Service Platform 1.0:sudo","SUSE Container as a Service Platform 2.0:sudo","SUSE Enterprise Storage 6:sudo","SUSE Enterprise Storage 6:sudo-devel","SUSE Linux Enterprise Desktop 12 SP4:sudo","SUSE Linux Enterprise Desktop 12 SP4:sudo-devel","SUSE Linux Enterprise Desktop 15 SP1:sudo","SUSE Linux Enterprise Desktop 15 SP1:sudo-devel","SUSE Linux Enterprise Desktop 15:sudo","SUSE Linux Enterprise Desktop 15:sudo-devel","SUSE Linux Enterprise High Performance Computing 12 SP4:sudo","SUSE Linux Enterprise High Performance Computing 15 SP1:sudo","SUSE Linux Enterprise High Performance Computing 15 SP1:sudo-devel","SUSE Linux Enterprise High Performance Computing 15:sudo","SUSE Linux Enterprise High Performance Computing 15:sudo-devel","SUSE Linux Enterprise Module for Basesystem 15 SP1:sudo","SUSE Linux Enterprise Module for Basesystem 15 SP1:sudo-devel","SUSE Linux Enterprise Module for Basesystem 15:sudo","SUSE Linux Enterprise Module for Basesystem 15:sudo-devel","SUSE Linux Enterprise Server 11 SP1 for Teradata:sudo","SUSE Linux Enterprise Server 11 SP3 for Teradata:sudo","SUSE Linux Enterprise Server 11 SP4 LTSS:sudo","SUSE Linux Enterprise Server 12 SP1-LTSS:sudo","SUSE Linux Enterprise Server 12 SP2-LTSS:sudo","SUSE Linux Enterprise Server 12 SP3-LTSS:sudo","SUSE Linux Enterprise Server 12 SP4:sudo","SUSE Linux Enterprise Server 12 SP4:sudo-devel","SUSE Linux Enterprise Server 12 SP5:sudo","SUSE Linux Enterprise Server 15 SP1:sudo","SUSE Linux Enterprise Server 15 SP1:sudo-devel","SUSE Linux Enterprise Server 15:sudo","SUSE Linux Enterprise Server 15:sudo-devel","SUSE Linux Enterprise Server Teradata 12 SP3:sudo","SUSE Linux Enterprise Server for SAP Applications 12 SP3:sudo","SUSE Linux Enterprise Server for SAP Applications 12 SP4:sudo","SUSE Linux Enterprise Server for SAP Applications 12 SP4:sudo-devel","SUSE Linux Enterprise Server for SAP Applications 15 SP1:sudo","SUSE Linux Enterprise Server for SAP Applications 15 SP1:sudo-devel","SUSE Linux Enterprise Server for SAP Applications 15:sudo","SUSE Linux Enterprise Server for SAP Applications 15:sudo-devel","SUSE Linux Enterprise Software Development Kit 12 SP4:sudo","SUSE Linux Enterprise Software Development Kit 12 SP4:sudo-devel","SUSE Manager Proxy 4.0:sudo","SUSE Manager Proxy 4.0:sudo-devel","SUSE Manager Retail Branch Server 4.0:sudo","SUSE Manager Retail Branch Server 4.0:sudo-devel","SUSE Manager Server 4.0:sudo","SUSE Manager Server 4.0:sudo-devel"]},"references":[{"category":"external","summary":"CVE-2019-18684","url":"https://www.suse.com/security/cve/CVE-2019-18684"},{"category":"external","summary":"SUSE Security Ratings","url":"https://www.suse.com/support/security/rating/"},{"category":"external","summary":"SUSE Bug 1155886 for CVE-2019-18684","url":"https://bugzilla.suse.com/1155886"}],"threats":[{"category":"impact","date":"2019-11-05T09:52:24Z","details":"moderate"}],"title":"CVE-2019-18684"}]}
