Uncontrolled Resource Consumption in Samsung rlottie

Executive Summary

This vulnerability is an uncontrolled resource consumption issue in Samsung's rlottie library. It allows excessive allocation due to repeaters in Lottie animations multiplying shapes up to 10,000 copies, each with up to 1,024 points. This can cause extremely high render costs per frame, leading to system resource exhaustion.

Detection Guidance

This vulnerability is specific to the rlottie library and relates to excessive resource consumption during Lottie animation rendering. Detection involves checking for unusually high CPU or memory usage when processing Lottie animations, particularly those with repeaters or complex shapes. Monitor for processes consuming excessive resources during animation playback.

Impact Analysis

This vulnerability can impact you by causing system slowdowns, crashes, or denial of service due to excessive CPU and memory usage during the rendering of malicious or complex Lottie animations. Normal animations remain unaffected.

Compliance Impact

The vulnerability does not directly impact compliance with GDPR or HIPAA. It primarily causes system resource exhaustion due to excessive render workloads in Lottie animations, which could lead to denial-of-service conditions. Compliance implications would depend on how the affected system is used in a regulated environment, but the vulnerability itself is not a direct violation of these standards.

Mitigation Strategies

Update the rlottie library to the patched version that introduces a shared budget of 15,000 weighted points to prevent excessive render workloads from repeaters in Lottie animations.
