CWEhttps://cwe.mitre.org/data/definitions/59.html

A vulnerability was found in buildah. Incorrect following of symlinks while reading .containerignore and .dockerignore results in information disclosure.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Name Vendor Start Version End Version
Podman Podman_project 4.3.0 (including) 4.3.0 (including)

Potential Mitigations

  • Follow the principle of least privilege when assigning access rights to entities in a software system.
  • Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
