Apple today released macOS Big Sur 11.2.1 to the public, alongside supplemental updates for macOS Catalina 10.15.7 and macOS Mojave 10.14.6. In addition to a fix for MacBook Pro charging issues, the update also brings a notable security fix for a Sudo bug that was reported last week.
Wardle told CyberScoop that “it has the potential to be the most impactful bug to everyday macOS users.” The issue existed due to a logic bug that made it so hackers could target users with malicious applications that bypass Apple ’s efforts to block bad applications, according to Wardle.
As we explained last week, the Sudo bug could allow an ordinary user to gain root access to a Mac, though an attacker would also need to combine with malware or a brute-force attack to gain user access in the first place. ZDNet explained the vulnerability:
The vulnerability, disclosed last week as CVE-2021-3156 (aka Baron Samedit) by security researchers from Qualys, impacts Sudo, an app that allows admins to delegate limited root access to other users. Qualys researchers discovered that they could trigger a “heap overflow” bug in the Sudo app to change the current user’s low-privileged access to root-level commands, granting the attacker access to the whole system
