SCA: security update for vllm (GHSA-9pcc-gvx5-r5wm)
high Tenable Cloud Security Plugin ID 436260
Description
There are packages installed that are affected by a vulnerability referenced in the following CVE:- vLLM is an inference and serving engine for large language models. In a multi-node vLLM deployment using
the V0 engine, vLLM uses ZeroMQ for some multi-node communication purposes. The secondary vLLM hosts open
a `SUB` ZeroMQ socket and connect to an `XPUB` socket on the primary vLLM host. When data is received on
this `SUB` socket, it is deserialized with `pickle`. This is unsafe, as it can be abused to execute code
on a remote machine. Since the vulnerability exists in a client that connects to the primary vLLM host,
this vulnerability serves as an escalation point. If the primary vLLM host is compromised, this
vulnerability could be used to compromise the rest of the hosts in the vLLM deployment. Attackers could
also use other means to exploit the vulnerability without requiring access to the primary vLLM host. One
example would be the use of ARP cache poisoning to redirect traffic to a malicious endpoint used to
deliver a payload with arbitrary code to execute on the target machine. Note that this issue only affects
the V0 engine, which has been off by default since v0.8.0. Further, the issue only applies to a deployment
using tensor parallelism across multiple hosts, which we do not expect to be a common deployment pattern.
Since V0 is has been off by default since v0.8.0 and the fix is fairly invasive, the maintainers of vLLM
have decided not to fix this issue. Instead, the maintainers recommend that users ensure their environment
is on a secure network in case this pattern is in use. The V1 engine is not affected by this issue.
