Slackware: 2020-031-01: sudo Security Update
Summary
Here are the details from the Slackware 14.2 ChangeLog: patches/packages/sudo-1.8.31-i586-1_slack14.2.txz: Upgraded. This update fixes a security issue: In Sudo before 1.8.31, 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 some Linux distributions; however, it is not the default for upstream or in Slackware, 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. For more information, see: https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2019-18634 (* Security fix *)
