Detailsinfo

A vulnerability was found in Apple Watch up to 1.0.2 (Smartwatch Operating System). It has been rated as critical. This issue affects some unknown functionality of the component ICU. The manipulation with an unknown input leads to a memory corruption vulnerability. Using CWE to declare the problem leads to CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer.
