Security Vulnerabilities - CVEs Published In 2021
containerd is a container runtime. A bug was found in containerd versions prior to 1.4.8 and 1.5.4 where pulling and extracting a specially-crafted container image can result in Unix file permission changes for existing files in the host’s filesystem. Changes to file permissions can deny access to the expected owner of the file, widen access to others, or set extended bits like setuid, setgid, and sticky. This bug does not directly allow files to be read, modified, or executed without an additional cooperating process. This bug has been fixed in containerd 1.5.4 and 1.4.8. As a workaround, ensure that users only pull images from trusted sources. Linux security modules (LSMs) like SELinux and AppArmor can limit the files potentially affected by this bug through policies and profiles that prevent containerd from interacting with specific files.

PwnDoc all versions until 0.4.0 (2021-08-23) has incorrect JSON Webtoken handling, leading to incorrect access control. With a valid JSON Webtoken that is used for authentication and authorization, a user can keep his admin privileges even if he is downgraded to the "user" privilege. Even after a user's account is deleted, the user can still access the administration panel (and add or delete users) and has complete access to the system.
