Apple iOS < 15 Multiple Vulnerabilities (HT212814)

high Nessus Plugin ID 153507


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


The version of Apple iOS running on the mobile device is prior to 15. It is, therefore, affected by multiple vulnerabilities, as follows:

- A buffer overflow when processing a maliciously crafted image may lead to arbitrary code execution. (CVE-2021-30847)

- A memory corruption issue may allow an attacker to execute arbitrary code on the system via maliciously crafted web content. (CVE-2021-30851)
- A race condition on the Kernel may allow a malicious application execute arbitrary code with kernel privileges. (CVE-2021-30857)

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


Upgrade to Apple iOS version 15 or later
