CVE-2025-0634
📋 TL;DR
A Use After Free vulnerability in Samsung's rLottie animation library allows remote attackers to execute arbitrary code by exploiting memory corruption. This affects all applications using rLottie version 0.2 to render animated content. Attackers can potentially take full control of affected systems.
💻 Affected Systems
- Samsung rLottie library
- Applications embedding rLottie for animation rendering
📦 What is this software?
Rlottie by Samsung
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution leading to complete system compromise, data theft, and lateral movement within networks.
Likely Case
Application crash (denial of service) or limited code execution within the application context.
If Mitigated
Application crash without code execution if memory protections like ASLR are effective.
🎯 Exploit Status
Exploitation requires crafting malicious animation files, but no public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Fixed in commit 507ea027e47d3e1dc7ddbd9994621215eae7ebb9 and later versions
Vendor Advisory: https://github.com/Samsung/rlottie/pull/571
Restart Required: Yes
Instructions:
1. Update rLottie to latest version from GitHub. 2. Rebuild and redeploy any applications using rLottie. 3. Restart affected applications/services.
🔧 Temporary Workarounds
Disable rLottie animation processing
allTemporarily disable or block animation file processing in applications using rLottie.
Application-specific configuration required
🧯 If You Can't Patch
- Isolate affected systems from untrusted networks
- Implement strict input validation for animation files
🔍 How to Verify
Check if Vulnerable:
Check if applications link to rLottie version 0.2 via dependency checking tools or by examining library versions.Check Version:
Check build configuration or use: ldd <application> | grep rlottie (Linux) or equivalent dependency checkVerify Fix Applied:
Verify rLottie version is newer than commit 507ea027e47d3e1dc7ddbd9994621215eae7ebb9.📡 Detection & Monitoring
Log Indicators:
- Application crashes with memory access violations
- Unexpected process termination when processing animation files
Network Indicators:
- Unusual outbound connections from applications using rLottie
SIEM Query:
Process termination events from applications known to use rLottie OR network connections from such applications to suspicious IPs
