Advisory Updated Date: 2020-03-18 22:00 Pacific
Severity:
Important
References:
CVE-2019-18634
Issue Overview:
In Sudo before 1.8.26, if pwfeedback is enabled in /etc/sudoers, users can trigger a stack-based buffer overflow in the privileged sudo process. (pwfeedback is a default setting in Linux Mint and elementary OS; however, it is NOT the default for upstream and many other packages, and would exist only if enabled by an administrator.) The attacker needs to deliver a long string to the stdin of getln() in tgetpass.c. (CVE-2019-18634)
Affected Packages:
sudo
