autogluon.multimodal vulnerable to unsafe YAML deserialization
### Impact
A potential unsafe deserialization issue exists within the `autogluon.multimodal` module, where YAML files are loaded via `yaml.load()` instead of `yaml.safe_load()`. The deserialization of untrusted data may allow an unprivileged third party to cause remote code execution, denial of service, and impact to both confidentiality and integrity.
Impacted versions: `>=0.4.0;<0.4.3`, `>=0.5.0;<0.5.2`.
### Patches
The patches are included in `autogluon.multimodal==0.4.3`, `autogluon.multimodal==0.5.2` and Deep Learning Containers `0.4.3` and `0.5.2`.
### Workarounds
Do not load data which originated from an untrusted source, or that could have been tampered with. **Only load data you trust.**
