Synopsis

The version of iOS running on the mobile device is affected by multiple vulnerabilities.

Description

The version of iOS running on the mobile device is prior to 9.3.5. It is, therefore, affected by multiple vulnerabilities :

- An information disclosure vulnerability exists in the kernel due to improper sanitization of user-supplied input. An unauthenticated, remote attacker can exploit this, by convincing a user to run a specially crafted application, to disclose sensitive information from kernel memory. (CVE-2016-4655)

- A remote code execution vulnerability exists in the kernel due to a memory corruption issue. An unauthenticated, remote attacker can exploit this by convincing a user to run a specially crafted application, to cause a denial of service condition or execution of arbitrary code. (CVE-2016-4656)

- A remote code execution vulnerability exists in WebKit due to a memory corruption issue. An unauthenticated, remote attacker can exploit this, by convincing a user to visit a malicious website, to cause a denial of service condition or execution of arbitrary code. (CVE-2016-4657)

These three zero day vulnerabilities were disclosed on 2016/08/25 and are known to be used by the NSO Group's spyware product Pegasus.

Solution

Upgrade to Apple iOS version 9.3.5 or later.
