Detail

Synopsis

Multiple vulnerabilities have been found in sudo, the worst of which could result in privilege escalation.

Background

sudo (su "do") allows a system administrator to delegate authority to give certain users (or groups of users) the ability to run some (or all) commands as root or another user while providing an audit trail of the commands and their arguments.

Description

Multiple vulnerabilities have been discovered in sudo. Please review the CVE identifiers referenced below for details.

Impact

A local attacker could expose or corrupt memory information, inject code to be run as a root user or cause a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All sudo users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.31"
