Apple has released security updates for MacOS Big Sur (11.5), Catalina (10.15) and Mojave, as well as iOS and iPadOS (14.7) and 14.7. There is no indication that Apple has fixed any vulnerabilities that may be exploited to deliver NSO Group’s Pegasus spyware via ‘zero-click’ iMessage attacks. Some of these may allow malicious applications to gain root privileges, or allow a sandboxed process to circumvent restrictions.
