Severity: High (CVSS:7.5)
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: System compromise, potential data leakage

Affected Products

Product | Affected Versions

rust-ffmpeg | 0.3.0 (after commit 5ac0527)

How the Exploit Works

The vulnerability stems from a null pointer dereference in the `name()` method of rust-ffmpeg 0.3.0. This method fails to handle NULL return values from the `av_get_sample_fmt_name()` C function properly. By providing an unrecognized sample format, an attacker can trigger this vulnerability and cause a DoS condition.

Conceptual Example Code

Below is a conceptual example of how the vulnerability might be exploited using a malformed multimedia file:

use std::process::Command;
use rust_ffmpeg::format::input;
let mut file = input("malformed_file.ff").unwrap();
let stream = file.streams().best_audio().unwrap();
let codec = stream.codec().unwrap();
// Triggering the vulnerability
let name = codec.sample_fmt().name().unwrap();

In the above pseudocode, `malformed_file.ff` is a file with an unrecognized sample format. When processed, it causes the `name()` method to encounter a NULL value, triggering a DoS condition.
