CVE-2025-53074

9.1 CRITICAL

📋 TL;DR

An out-of-bounds read vulnerability in Samsung's rLottie animation library (version 0.2) allows attackers to read memory beyond allocated buffers. This could lead to information disclosure or be chained with other vulnerabilities for more severe attacks. Any application using the vulnerable rLottie library is affected.

💻 Affected Systems

Products:
  • Samsung rLottie library
Versions: Version 0.2
Operating Systems: All platforms using rLottie
Default Config Vulnerable: ⚠️ Yes
Notes: Only affects applications that use rLottie for rendering Lottie animations. Not all Samsung devices may use this library.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Memory disclosure leading to sensitive data exposure, potential ASLR bypass, or crash causing denial of service. Could be combined with other vulnerabilities for remote code execution.

🟠

Likely Case

Application crash causing denial of service, or limited memory disclosure of adjacent data structures.

🟢

If Mitigated

Application crash with no data loss if proper sandboxing and memory protections are enabled.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: LOW

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Out-of-bounds read vulnerabilities typically require specific conditions to be exploitable. The GitHub PR shows the fix but doesn't include exploit details.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Fixed in commit referenced in PR #571

Vendor Advisory: https://github.com/Samsung/rlottie/pull/571

Restart Required: Yes

Instructions:

1. Update rLottie to version containing fix from PR #571
2. Rebuild any applications using rLottie
3. Restart affected services or applications

🔧 Temporary Workarounds

Disable rLottie rendering

all

Temporarily disable Lottie animation rendering in affected applications

Memory protection hardening

linux

Enable ASLR and other memory protection mechanisms

sysctl -w kernel.randomize_va_space=2

🧯 If You Can't Patch

  • Network segmentation to isolate systems using rLottie
  • Implement application allowlisting to prevent unauthorized code execution

🔍 How to Verify

Check if Vulnerable:

Check if application uses rLottie version 0.2 via dependency checking or version strings

Check Version:

Check build configuration or dependency files for rLottie version

Verify Fix Applied:

Verify rLottie has been updated to version containing fix from PR #571

📡 Detection & Monitoring

Log Indicators:

  • Application crashes with memory access violations
  • Segmentation faults in rLottie processes

Network Indicators:

  • Unusual network traffic to/from applications using rLottie

SIEM Query:

process_name:"*lottie*" AND (event_type:crash OR memory_violation)
