vLLM is an inference and serving engine for large language models (LLMs). From 0.8.3 to before 0.14.1, when an invalid image is sent to vLLM's multimodal endpoint, PIL throws an error. vLLM returns this error to the client, leaking a heap address. With this leak, we reduce ASLR from 4 billion guesses to ~8 guesses. This vulnerability can be chained a heap overflow with JPEG2000 decoder in OpenCV/FFmpeg to achieve remote code execution. This vulnerability is fixed in 0.14.1.

GHSA-4r2x-xpjr-7cvv — vLLM has RCE In Video Processing

Affected: PyPI: vllm

## Summary

**A chain of vulnerabilities in vLLM allow Remote Code Execution (RCE):**

1. **Info Leak** - PIL error messages expose memory addresses, bypassing ASLR 2. **Heap Overflow** - JPEG2000 decoder in OpenCV/FFmpeg has a heap overflow that lets us hijack code execution

**Result:** Send a malicious video URL to vLLM Completions or Invocations **for a video model** -> Execute arbitrary commands on the server

Completely default vLLM instance directly from pip, or docker, does not have authentication so "None" privileges are required, but even with non-default api-key enabled configuration this exploit is feasible through invocations route that allows payload to execute pre-auth.

Example heap target is provided, other heap targets can be exploited as well to achieve rce. Leak allows for simple ASLR bypass. Leak + heap overflow achieves RCE on versions prior to 0.14.1.

Deployments not serving a video model are not affected.

## 1. Vulnerability Overview

### 1.1 The Bug: JPEG2000 cdef Box Heap Overflow The JPEG2000 decoder used by OpenCV (cv2) honors a `cdef` box that can remap color channels. When Y (luma) is mapped into the U (chroma) plane buffer, the decoder writes a large Y plane into the smaller U buffer, causing a heap overflow.

**Root Cause** - `cdef` allows channel remapping (e.g., Y→U, U→Y). - Y plane size: `W×H`; U plane size: `(W/2)×(H/2)`. - Overflow size = `W×H - (W/2×H/2)` = `0.75 × W × H` bytes.

**Example (150×64)** - Y plane: 150×64 = 9,600 b…
