Description

P30 smart phones with versions earlier than ELLE-AL00B 9.1.0.193(C00E190R2P1) have an integer overflow vulnerability due to insufficient check on specific parameters. An attacker tricks the user into installing a malicious application, obtains the root permission and constructs specific parameters to the camera program to exploit this vulnerability. Successful exploit could cause the program to break down or allow for arbitrary code execution.

• 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.
