CVE-2021-41150: Amazon Tough

Medium severity, CVSS 6.5. EPSS: 1.3% chance of exploitation in the next 30 days.

Tough provides a set of Rust libraries and tools for using and generating the update framework (TUF) repositories. The tough library, prior to 0.12.0, does not properly sanitize delegated role names when caching a repository, or when loading a repository from the filesystem. When the repository is cached or loaded, files ending with the .json extension could be overwritten with role metadata anywhere on the system. A fix is available in version 0.12.0. No workarounds to this issue are known.

Affected products

• Amazon Tough: before 0.12.0 (fixed in 0.12.0)
