CVE-2025-53074
📋 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
- Samsung rLottie library
📦 What is this software?
Rlottie by Samsung
⚠️ 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.
🎯 Exploit Status
Out-of-bounds read vulnerabilities typically require specific conditions to be exploitable. The GitHub PR shows the fix but doesn't include exploit details.
