Description

A low privileged remote attacker can execute arbitrary code by sending specially crafted calls to the web service of the Device Manager or locally via an API and can cause integer overflows which then may lead to arbitrary code execution within privileged processes.

• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
