  script_tag(name:"insight", value:"A confidential data leak vulnerability was found in Docker CLI. The execution of docker login to a private registry may send provided credentials in a misconfigured docker credentials store to the registry-1.docker.io rather than the specified private registry. This flaw allows an attacker to steal private registry credentials. The highest threat from this vulnerability is to confidentiality.(CVE-2021-41092)

A file permissions vulnerability was found in the Moby (Docker Engine). The Moby data directory (usually /var/lib/docker) contains subdirectories with insufficiently restricted permissions, allowing unprivileged Linux users to traverse directory contents and execute programs. When the running container contains executable programs with the extended permission bits (like setuid), unprivileged Linux users can discover and execute those programs. Additionally, when the UID of an unprivileged Linux user on the host collides with the file owner or group inside a container, the unprivileged Linux user on the host can discover, read, and modify those files. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.(CVE-2021-41091)

A file permissions vulnerability was found in Moby (Docker Engine). Copying files by using docker cp into a specially-crafted container can result in Unix file permission changes for existing files in the host's filesystem, which might lead to permissions escalation and allow an attacker access to restricted data.(CVE-2021-41089)");
