Insufficient validation of an attacker-controlled\nboundary parameter may allow a remote unauthenticated attacker to submit a\ncrafted request that corrupts memory by overwriting data beyond the bounds of\nan internal buffer.\n\n\n\n\n\n\n\n\n\nSuccessful\nexploitation may result in modification or corruption of process memory,\npotentially leading to undefined application behavior.
