Title: sudo: Unauthorized privilege escalation in sudoedit (GLSA 201606-13)
Date: June 26, 2016
sudo is vulnerable to an escalation of privileges via a symlink
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.
Vulnerable: < 1.8.15-r1
Unaffected: >= 1.8.15-r1
Architectures: All supported architectures
sudoedit in sudo is vulnerable to the escalation of privileges by local
users via a symlink attack. This can be exploited by a file whose full
path is defined using multiple wildcards in /etc/sudoers, as demonstrated
Local users are able to gain unauthorized privileges on the system.
There is no known work around at this time.
All sudo users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.15-r1"
