EulerOS 2.0 SP9 : sudo (EulerOS-SA-2020-2237)

high Nessus Plugin ID 141764

Synopsis

The remote EulerOS host is missing a security update.

Description

According to the version of the sudo package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

 - 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)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected sudo package.
