CVE-2025-53076
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 · uneditedImproper Input Validation vulnerability in Samsung Open Source rLottie allows Overread Buffers.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 confidencerLottie V0.2 contains an Improper Input Validation vulnerability that allows buffer overreading. The library fails to properly validate input bounds when parsing data, causing reads beyond allocated memory boundaries. This critical flaw is network-exploitable without authentication or user interaction.

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.
-
Identify rLottie library installationSearch for files named 'lottie', 'rlottie', or 'rlottie.so' in common library paths such as /usr/lib/, /usr/local/lib/, or within application bundling directories. Also check dependency lists of applications that may link to rLottie.Affected if rLottie library version 0.2 is found on the system
-
Determine installed rLottie versionRun 'strings' on the library binary and search for version strings, or check package management tools (dpkg, rpm, pkg-config) if rLottie was installed via a package manager with 'pkg-config --modversion rlottie' or equivalent.Affected if The reported version is exactly 0.2
-
Verify lottie parsing functionality is in useReview application logs, code, or configuration to confirm that rLottie is actively parsing lottie JSON animation data. Check if applications link against and call rLottie APIs such as LottieAnimation or rLottie_parse.Affected if Applications parse lottie animation data using rLottie
-
Assess input exposureDetermine whether the rLottie parsing receives input from untrusted sources such as network requests, user-uploaded files, or external APIs. Inspect network-exposed services or file upload handlers that process lottie files.Affected if rLottie processes lottie data from untrusted or network-accessible sources without prior sanitization
The system is affected if rLottie version 0.2 is installed and actively parsing lottie data from any untrusted or network-accessible input source.

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.
dbcve · scopedUpgrade rLottie to a patched version if available; otherwise, implement strict input validation and bounds checking in all parsing routines to prevent overread conditions.
- Obtain the fix from the vendor patch at https://github.com/Samsung/rlottie/pull/573
- Apply the patch to the rLottie v0.2 source code to address the improper input validation leading to buffer overread
