Stack-based buffer overflow in Baidu Spark Browser 26.5.9999.3511 allows remote attackers to cause a denial of service (application crash) via nested calls to the window.print JavaScript function.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
