Executive brief
Samsung rlottie, a library used for rendering vector-based animations, contains a vulnerability that can lead to excessive memory consumption. If a user is tricked into opening a specially crafted animation file, the application may attempt to allocate an enormous amount of memory, potentially causing the device or application to crash. This impact primarily affects the availability of the service or device, leading to a denial-of-service condition.
Technical details
A vulnerability classified as CWE-789 (Memory Allocation with Excessive Size Value) exists in Samsung's rlottie library. The flaw occurs when the library processes input that specifies an extremely large size for memory allocation, which the application fails to properly validate. An attacker can exploit this by providing a malicious Lottie animation file that, when rendered, triggers an excessive allocation request. This is a local attack vector requiring user interaction (opening the file) and results in a high impact on availability (DoS) due to resource exhaustion. The issue was addressed in the master branch prior to commit 0b4e308fa88c72cbb60cc8a2c1d2c2ad89b101dd.
