Root Access Sudo Bug Found to Affect macOS Big Sur
A sudo bug that can grant an attacker root access has been discovered to affect macOS Big Sur (via ZDNet). The security vulnerability, identified last week as "CVE-2021-3156" by the Qualys Security Team, affects sudo, which is a program that allows users to run commands with the security privileges of another user, such as an administrator. The bug triggers a "heap overflow" in sudo that changes the current user's privileges to enable root-level access.
