Apple to Patch Web Browser Vulnerabilities Affecting Recent Macs, iPads and iPhones
There are two new speculative execution attacks that impact recent Apple chips, according to data shared today by Georgia Tech students that discovered the vulnerabilities.
Named SLAP and FLOP, the two security flaws could allow an attacker to use a malicious webpage to spy on the contents of other webpages, giving attackers remote access to browsing history, credit card data, emails, location information, and more. Physical access to a device is not required, and the attack can be executed through a malicious site that bypasses Apple's browser protections.
Several Apple A-series and M-series chips are affected, including the M2 and later and the A15 and later, which are in the following devices:
- 2022 and later Mac notebooks
- 2023 and later Mac desktops
- 2021 and later iPad models
- 2021 and later iPhones
SLAP and FLOP were disclosed to Apple in May 2024 and September 2024, respectively, and while the attacks have not yet been patched, the researchers who reported the issue were told that Apple plans to address the vulnerabilities in an upcoming security update.
Apple told Bleeping Computer that it has not yet patched the flaws. "We want to thank the researchers for their collaboration as this proof of concept advances our understanding of these types of threats," Apple said. "Based on our analysis, we do not believe this issue poses an immediate risk to our users."
SLAP affects Safari, while FLOP affects Safari and Chrome. Other browsers like Firefox could be affected too, but have not been tested. There is no evidence that SLAP and FLOP have been executed in the wild.
Details on how SLAP and FLOP work can be found on the website dedicated to explaining the vulnerabilities.
