A recently discovered root exploit vulnerability in Linux has been found to affect Apple Inc.’s macOS as well.
The vulnerability allows for an attacker to trigger a so-called heap overflow in Sudo, a program for Unix-like computer operating systems. It allow users to run security privileges of another user in order to gain access to other accounts on the operating system to which they shouldn’t otherwise have access.
Researchers at Qualysis Inc. first identified the vulnerability Jan. 26 and said that they had found it in Ubuntu 20.04 (Sudo 1.8.31), Debian 10 (Sudo 1.8.27) and Fedora 33 (Sudo 1.9.2) but also noted that it may affect other operating systems. Matthew Hickey, the co-founder of Hacker House, has since discovered that the vulnerability also affects macOS Big Sur, demonstrating Tuesday on Twitter how he was able to exploit it.

MacOS has its roots in Unix and includes Sudo support, hence why it’s also vulnerable. Exactly how many versions of macOS are vulnerable, however, is unknown. The Sudo vulnerability itself is believed to have existed for at least 10 years before being discovered.

“By itself, a privilege escalation vulnerability might not be especially dangerous for most users,” Jonathan Knudsen, a technical evangelist at electronic design automation company Synopsys Inc., told SiliconANGLE. “It could only be exploited if an attacker already has access to your computer, either locally or through a remote shell.”
Chained together with one or more other exploits, though, that risk could be multiplied, he added. “If an attacker exploits another vulnerability to run code as a regular user, then they can trivially run the exploit for CVE-2021-3156 to gain administrative access, allowing them to take complete control of your computer,” he said,
