A potential memory corruption and crash when using Skia content when drawing content outside of the bounds of a clipping region. This vulnerability affects Thunderbird < 52.1, Firefox ESR < 52.1, and Firefox < 53.
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.
