Technical details
An integer overflow vulnerability exists in Samsung's rlottie library when calculating bitmap buffer sizes for animation rendering. The vulnerability occurs during stride and buffer size computation, where large dimension values in animation files can overflow integer calculations and result in undersized buffer allocation. An attacker can craft a malicious Lottie animation file with extremely large dimensions to trigger the overflow; no authentication or user interaction is required beyond processing the file. The fix, merged in August 2026, caps bitmap dimensions to reject requests larger than 128 MB and uses 64-bit arithmetic for calculations to prevent overflow.
