Synopsis

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

Description

The version of Apple iOS running on the mobile device is prior to 14.8. It is, therefore, affected by multiple vulnerabilities, including the following:

 - A use after free issue due to incorrect memory management, which can lead to arbitrary code execution when processing maliciously crafted web content. (CVE-2021-30858)

 - An integer overflow issue due to insufficient input validation, which can lead to arbitrary code execution when processing a maliciously crafted PDF. (CVE-2021-30860)

 - Arbitrary code execution when processing a maliciously crafted dfont file. (CVE-2021-30841, CVE-2021-30842, CVE-2021-30843)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apple iOS version 14.8 or later
