The FileReader class in Mozilla Firefox before 45.0 allows local users to gain privileges or cause a denial of service (memory corruption) by changing a file during a FileReader API read operation.
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.
