Alpine: multiple sudo packages: security update to 1.8.23-r4

high Tenable Cloud Security Plugin ID 407277

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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.
