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 12.5.5. It is, therefore, affected by multiple vulnerabilities, as follows:

- An integer overflow was addressed with improved input validation. Processing a maliciously crafted PDF may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited. (CVE-2021-30860)

- A use after free issue was addressed with improved memory management. Processing maliciously crafted web content may lead to arbitrary code execution. Apple is aware of a report that this issue may have been actively exploited. (CVE-2021-30858)

- Incorrect state handling lead to a type confusing issue that allows a malicious application to execute arbitrary code with kernel privileges. (CVE-2021-30869)

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 12.5.5 or later
