2021-01-27 sudo security release: Buffer overflow in command line unescaping
On January 26, the Sudo developers released a new sudo utility version that contains a security fix. It is highly recommended to upgrade the sudo package in your system to this latest version.
Sudo versions 1.8.2 through 1.8.31p2 and 1.9.0 through 1.9.5p1 are affected by the sudo unescape overflow issue (CVE-2021-3156).
The bug can be leveraged to elevate privileges to root, even if the user is not listed in the sudoers file. User authentication is not required to exploit the bug.
