macOS 11.x < 11.2.3 (HT212220)

high Nessus Plugin ID 147658

Synopsis

The remote host is missing a macOS security update.

Description

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.2.3 Big Sur. It is, therefore, affected by a memory corruption issue due to insufficient validation. An attacker can exploit this with crafted web content to cause arbitrary code execution.

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

Solution

Upgrade to macOS 11.2.3 or later.
