GLSA-200506-22 : sudo: Arbitrary command execution

medium Nessus Plugin ID 18549

Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200506-22 (sudo: Arbitrary command execution)

The sudoers file is used to define the actions sudo users are permitted to perform. Charles Morris discovered that a specific layout of the sudoers file could cause the results of an internal check to be clobbered, leaving sudo vulnerable to a race condition.
Impact :

Successful exploitation would permit a local sudo user to execute arbitrary commands as another user.
Workaround :

Reorder the sudoers file using the visudo utility to ensure the 'ALL' pseudo-command precedes other command definitions.

Solution

All sudo users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose '>=app-admin/sudo-1.6.8_p9'
