[slackware-security] sudo (SSA:2020-031-01)
New sudo packages are available for Slackware 14.0, 14.1, 14.2,
and -current to fix a security issue.
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 *)
