CVE-2020-15113 Open this link in a new tabHow to fix?
Upgrade Debian:unstable etcd to version 3.3.25+dfsg-5 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream etcd package and not the etcd package as distributed by Debian.
See How to fix? for Debian:unstable relevant fixed versions and status.
In etcd before versions 3.3.23 and 3.4.10, certain directory paths are created (etcd data directory and the directory path when provided to automatically generate self-signed certificates for TLS connections with clients) with restricted access permissions (700) by using the os.MkdirAll. This function does not perform any permission checks when a given directory path exists already. A possible workaround is to ensure the directories have the desired permission (700).
