Application crash via unchecked cubic arc splitting
Published Jun 4, 2026 · Updated Jun 4, 2026
Stack overflow in Samsung Open Source rlottie allows attackers to crash an application by supplying a malformed Lottie file. The gray_render_cubic function advances an arc pointer through bez_stack without checking that a cubic split leaves room, so gray_split_cubic writes beyond the stack array. A user must cause the application to render the crafted animation; the overflow corrupts process memory and interrupts the application.
