sudo: Information disclosure

Background

sudo allows a system administrator to give users the ability to run commands as other users. Access to commands may also be granted on a range to hosts.

Description

sudo does not handle the TZ environment variable properly.

Impact

A local attacker may be able to read arbitrary files or information from device special files.

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-1.8.12"
