On Samsung Galaxy S4 through S7 devices, an integer overflow condition exists within libomacp.so when parsing OMACP messages (within WAP Push SMS messages) leading to a heap corruption that can result in Denial of Service and potentially remote code execution, a subset of SVE-2016-6542.
The 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.
