SCA: security update for lmdeploy (GHSA-2vh9-42vm-xmv2)

critical Tenable Self-Hosted Container Security Plugin ID 448256

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- LMDeploy is a toolkit for compressing, deploying, and serving large language models. Starting in version
0.9.2 and prior to version 0.16.0, LMDeploy's PyTorch DistServe/PD-disaggregation control plane used
`recv_pyobj()` to deserialize messages received through a ZeroMQ PULL socket. PyZMQ implements
`recv_pyobj()` using Python pickle deserialization, which can execute arbitrary code while reconstructing
an object. The peer address used by the receiver was supplied through the `POST /distserve/p2p_connect`
HTTP endpoint. An attacker who could reach an affected DistServe API server could cause the server to
connect to an attacker-controlled ZeroMQ endpoint and deserialize a crafted pickle payload. API-key
authentication is not enabled unless the operator explicitly configures it. As a result, affected
DistServe deployments without API keys allowed unauthenticated remote code execution with the privileges
of the LMDeploy serving process. This issue affects the PyTorch backend when PD-disaggregation/DistServe
is enabled. Ordinary deployments that do not use the affected disaggregated-serving path do not expose
this data flow. The fix was released in LMDeploy 0.16.0. Users who cannot upgrade immediately should
prevent untrusted clients from reaching `/distserve/*` endpoints, restrict the DistServe HTTP and ZeroMQ
control planes to trusted cluster networks, configure API-key authentication, and block arbitrary outbound
ZeroMQ connections from serving nodes. These measures reduce exposure but do not make pickle
deserialization safe. (CVE-2025-66455)

Solution

Update the lmdeploy library and its related packages to version 0.16.0 or later.
