Описание
vLLM is an inference and serving engine for large language models (LLMs). In version 0.8.0 up to but excluding 0.9.0, the vLLM backend used with the /v1/chat/completions OpenAPI endpoint fails to validate unexpected or malformed input in the "pattern" and "type" fields when the tools functionality is invoked. These inputs are not validated before being compiled or parsed, causing a crash of the inference worker with a single request. The worker will remain down until it is restarted. Version 0.9.0 fixes the issue.
A denial of service flaw was found in vLLM. This flaw allows a remote attacker with access to /v1/chat/completions OpenAPI endpoint to submit malformed data in the "pattern" and "type" fields to crash the vLLM instance.
Отчет
The severity of this vulnerability is rated Moderate, as it does not impact system availability. The effects are confined to the application layer, without compromising the underlying system stability.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
