Test ID:	1.3.6.1.4.1.25623.1.1.10.2021.0500
Category:	Mageia Linux Local Security Checks
Title:	Mageia: Security Advisory (MGASA-2021-0500)
Summary:	The remote host is missing an update for the 'docker' package(s) announced via the MGASA-2021-0500 advisory.
Description:	Summary: The remote host is missing an update for the 'docker' package(s) announced via the MGASA-2021-0500 advisory. Vulnerability Insight: Updated docker packages fix security vulnerabilities: A bug was found in Moby (Docker Engine) where attempting to copy files using `docker cp` into a specially-crafted container can result in Unix file permission changes for existing files in the hosts filesystem, widening access to others. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process (CVE-2021-41089). A bug was found in Moby (Docker Engine) where the data directory (typically '/var/lib/docker') contained subdirectories with insufficiently restricted permissions, allowing otherwise unprivileged Linux users to traverse directory contents and execute programs. When containers included executable programs with extended permission bits (such as 'setuid'), unprivileged Linux users could discover and execute those programs. When the UID of an unprivileged Linux user on the host collided with the file owner or group inside a container, the unprivileged Linux user on the host could discover, read, and modify those files (CVE-2021-41091). A bug was found in the Docker CLI where running 'docker login my-private-registry.example.com' with a misconfigured configuration file (typically '~ /.docker/config.json') listing a 'credsStore' or 'credHelpers' that could not be executed would result in any provided credentials being sent to 'registry-1.docker.io' rather than the intended private registry (CVE-2021-41092). Affected Software/OS: 'docker' package(s) on Mageia 8. Solution: Please install the updated package(s). CVSS Score: 5.0 CVSS Vector: AV:N/AC:L/Au:N/C:P/I:N/A:N
