Apple iOS < 15.2 Multiple Vulnerabilities (HT212976)

high Nessus Plugin ID 156187


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 15.2. It is, therefore, affected by multiple vulnerabilities, including the following:

- Memory corruption issues exist in the processing of ICC profiles due to insufficient input validation.
This may lead to arbitrary code execution. (CVE-2021-30926, CVE-2021-30942)

- A buffer overflow issue exists when processing a maliciously crafted audio file. This may lead to arbitrary code execution. (CVE-2021-30957)

- An out-of-bounds read exists when playing a malicious audio file which may lead to arbitrary code execution. (CVE-2021-30958)

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 15.2 or later
