Vulnerability Summary

CVE ID: CVE-2025-57616
Severity: High (7.5)
Attack Vector: Remote
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

Rust-ffmpeg | 0.3.0

How the Exploit Works

The vulnerability exploits a use-after-free issue in the write_interleaved method of the rust-ffmpeg library. This is due to the method violating Rust’s aliasing rules by altering a data structure through a mutable pointer while solely holding an immutable reference. As a result, an attacker can remotely trigger undefined behavior when the data is accessed later, leading to potential denial of service or memory corruption.

Conceptual Example Code

An attacker might exploit the vulnerability by sending a specially crafted payload that triggers the use-after-free condition in the write_interleaved method. A simplified, conceptual example might look like this:

let mut data = Some(Data::new());
let reference = &data;
let pointer = &mut data;
// Trigger use-after-free issue
drop(reference);
write_interleaved(pointer, payload);

In this conceptual example, dropping the reference while still having a mutable pointer leads to a use-after-free condition when the write_interleaved method is called. This undefined behavior can lead to memory corruption or a denial of service, depending on the attacker’s payload and the system’s state.

Severity: High (7.5 CVSS)
Attack Vector: Remote
Privileges Required: None
User Interaction: No
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

rust-ffmpeg | 0.3.0 after commit 5ac0527

How the Exploit Works

The CVE-2025-57615 exploit takes advantage of an unchecked cast of a usize parameter to c_int in the Vector::new constructor function of rust-ffmpeg 0.3.0. This unchecked cast can lead to an integer overflow, resulting in a negative value being passed to the underlying C function sws_allocVec(). The result is a null pointer dereference that can cause a denial of service.

Conceptual Example Code

The following pseudocode demonstrates the concept of this vulnerability:

use rust_ffmpeg::Vector;
fn main() {
// Oversized usize value
let size: usize = usize::MAX;
// Unchecked cast to c_int
let vec = Vector::new(size as c_int);
// Call to vulnerable C function
vec.sws_allocVec();
}

This pseudocode does not represent an actual exploit but serves to illustrate the nature of the vulnerability. The oversized usize value triggers an integer overflow when cast to c_int, resulting in a negative value being passed to sws_allocVec() and leading to a null pointer dereference.

Overview

An integer overflow and invalid input vulnerability has been discovered in rust-ffmpeg version 0.3.0. This vulnerability could allow an attacker to cause a denial of service or potentially execute arbitrary code on the target system. This issue is particularly significant because it may lead to system compromise or data leakage, and it affects a wide range of systems running the specified version of rust-ffmpeg.

Vulnerability Summary

CVE ID: CVE-2025-57614
Severity: High, CVSS score 7.5
Attack Vector: Network
Privileges Required: None
User Interaction: None
Impact: Potential system compromise or data leakage

Affected Products

Product | Affected Versions

rust-ffmpeg | 0.3.0

How the Exploit Works

The vulnerability arises from an unchecked cast in rust-ffmpeg’s cached method when dimension parameters are zero or exceed i32::MAX. This violates the underlying C function’s preconditions and triggers undefined behavior, which in turn could allow an attacker to cause a denial of service or potentially execute arbitrary code on the target system.

Conceptual Example Code

Here is a conceptual code snippet that illustrates how an attacker might exploit the vulnerability:

use std::i32;
fn main() {
let mut cache = rust_ffmpeg::Cache::new();
// Overflow the i32::MAX limit
let large_dimension = i32::MAX + 1;
// Pass the overflowed value as a dimension parameter
cache.cached_method(large_dimension, large_dimension);
}

In this example, `large_dimension` is an integer that exceeds `i32::MAX`, and it’s passed as a parameter to the `cached_method()`. This will trigger an unchecked cast in the `cached_method()`, leading to undefined behavior that an attacker could exploit to cause a denial of service or execute arbitrary code.

Overview

Affected Products

Product | Affected Versions

rust-ffmpeg | 0.3.0

How the Exploit Works

The vulnerability resides in the `input()` constructor function of the rust-ffmpeg 0.3.0 library. If the `avio_alloc_context()` function call fails and returns NULL, this NULL is then stored and later dereferenced by the Io struct’s Drop implementation. An attacker can exploit this flaw by causing the `avio_alloc_context()` call to fail, hence triggering a null pointer dereference and causing a denial of service condition.

Conceptual Example Code

Here’s a conceptual representation of how an attacker might trigger this vulnerability:

// This is pseudocode and is not intended to be functional
fn main() {
let ffmpeg = rust_ffmpeg::input("malicious_input");
// The "malicious_input" causes avio_alloc_context() to fail and return NULL
// This NULL is then stored and later dereferenced, causing a denial of service
}

Mitigation

Users of the affected rust-ffmpeg version are advised to apply the vendor patch once it becomes available. Until then, the use of Web Application Firewalls (WAF) or Intrusion Detection Systems (IDS) can serve as a temporary mitigation measure to detect and prevent potential exploit attempts.

Overview

The following report discusses a critical vulnerability discovered in rust-ffmpeg 0.3.0. This vulnerability, designated as CVE-2025-57612, allows an attacker to induce a denial of service (DoS) by exploiting a null pointer dereference issue. Entities that rely on this software for multimedia processing are potentially at risk, and the potential for system compromise or data leakage makes this issue highly significant.

Vulnerability Summary

CVE ID: CVE-2025-57612
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.

Affected Products

Product | Affected Versions

Bevy Event Service | All versions up to 2025-07-22

How the Exploit Works

The vulnerability arises due to a misconfiguration in the SSO (Single Sign-On) system of the Bevy Event service. When a user changes their email address, an attacker can create their own account and perform an SSO login. This action allows the attacker to take over the victim’s account, potentially giving them unauthorized access to sensitive data or control over system operations.

Conceptual Example Code

Below is a hypothetical example of how the vulnerability might be exploited. This is a conceptual demonstration and does not represent an actual attack.

POST /sso/login HTTP/1.1
Host: bevy.example.com
Content-Type: application/json
{
"username": "attacker",
"password": "attacker_password",
"victim_email": "victim@victim.com"
}

In this example, the attacker attempts to log in using their own credentials but with the victim’s email. The misconfigured SSO system allows this login, leading to account takeover.
It’s crucial for users of the Bevy Event service to apply the vendor’s patch or use a WAF/IDS as a temporary mitigation strategy to protect themselves from potential exploits leveraging this vulnerability.
