The /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager when calculating ephemeral storage usage by a pod. If a pod writes a large amount of data to the /etc/hosts file, it could fill the storage space of the node and cause the node to fail.","title":"CVE description"}],"product_status":{"recommended":["SUSE Linux Enterprise Module for Containers 15 SP1:kubernetes-client-1.17.4-4.18.1.x86_64","SUSE Linux Enterprise Module for Containers 15 SP1:kubernetes-common-1.17.4-4.18.1.x86_64"]},"references":[{"category":"external","summary":"CVE-2020-8557","url":"https://www.suse.com/security/cve/CVE-2020-8557"},{"category":"external","summary":"SUSE Bug 1173984 for CVE-2020-8557","url":"https://bugzilla.suse.com/1173984"}],"remediations":[{"category":"vendor_fix","details":"To install this SUSE Security Update use the SUSE recommended installation methods like YaST online_update or \"zypper patch\".\n","product_ids":["SUSE Linux Enterprise Module for Containers 15 SP1:kubernetes-client-1.17.4-4.18.1.x86_64","SUSE Linux Enterprise Module for Containers 15 SP1:kubernetes-common-1.17.4-4.18.1.x86_64"]}],"scores":[{"cvss_v3":{"baseScore":5.5,"baseSeverity":"MEDIUM","vectorString":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"products":["SUSE Linux Enterprise Module for Containers 15 SP1:kubernetes-client-1.17.4-4.18.1.x86_64","SUSE Linux Enterprise Module for Containers 15 SP1:kubernetes-common-1.17.4-4.18.1.x86_64"]}],"threats":[{"category":"impact","date":"2020-08-11T12:33:40Z","details":"moderate"}],"title":"CVE-2020-8557"}]}
