CVE-2025-0634
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedUse After Free vulnerability in Samsung Open Source rLottie allows Remote Code Inclusion.This issue affects rLottie: V0.2.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceA Use After Free (UAF) vulnerability in Samsung's rLottie library version V0.2 allows remote code execution/inclusion. The UAF flaw enables an attacker to potentially control memory after it has been freed, leading to arbitrary code execution when the library parses malicious Lottie animation files.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Locate rLottie library on the systemSearch for librlottie.so (Linux), rlottie.dll (Windows), or librlottie.dylib (macOS) in common library directories (/usr/lib, /opt, or application bundles). Also check package managers (dpkg, rpm, brew) for rlottie packages.Affected if rLottie library file is found on the system
-
Identify installed rLottie versionRun 'rlottie-config --version' if available, or check the library file version metadata. On Linux: 'strings librlottie.so | grep -i version' or examine package version. Compare the discovered version to the affected range = 0.2.Affected if Installed version is exactly 0.2
-
Determine if applications use rLottieSearch application dependencies for rLottie linkage: 'ldd <application> | grep rlottie' or check application configuration files for Lottie rendering enablement. Identify which applications process Lottie animation files.Affected if An application that links to rLottie version 0.2 is installed and actively used to render Lottie files
-
Audit Lottie file processing activityReview application logs, network traffic, or file access records for processing of .json/.lottie Lottie animation files, as the UAF triggers when parsing specially crafted animation data.Affected if Lottie files from untrusted sources are being processed by rLottie 0.2
The environment is affected only if rLottie version 0.2 is installed AND actively processing Lottie animation files, enabling the UAF to trigger during malformed animation parsing.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade rLottie to a patched version; if no patch exists, limit exposure of applications using this library to untrusted Lottie files and consider compensating controls until a fix is available.
