The iPhone iOS 16.1.1 security update protects users against two vulnerabilities:
CVE-2022-40303
CVE-2022-40304
Both vulnerabilities have been found in libxml2, a software library for parsing XML documents and both were disclosed by Google’s Project Zero, Google’s team of cybersecurity researchers.
Both CVE-2022-40303 and CVE-2022-40304 could allow a remote user to cause unexpected app termination or arbitrary code execution – potentially enabling attackers to run commands on the device.
The vulnerabilities are classified under CVE ratings as having moderate impact, which means flaws that might be more difficult to exploit but that could still lead to compromise.
Apple doesn’t detail how exactly the vulnerabilities work or what exactly has been done to fix them, citing how, “For our customers’ protection, Apple doesn’t disclose, discuss, or confirm security issues until an investigation has occurred and patches or releases are available.”
Apple’s release notes say that applying the update, which also brings unspecified bug fixes, is “recommended for all users”.
