What is GHSA-6h2x-4gjf-jc5w?
GHSA-6h2x-4gjf-jc5w is an unsafe deserialization vulnerability in autogluon-multimodal, published on 21 Sep 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
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.
