Vulnerability Assessment Details

[GLSA-200506-22] sudo: Arbitrary command execution

Vulnerability Assessment Summary
sudo: Arbitrary command execution

Detailed Explanation for this Vulnerability Assessment
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"


Network Security Threat Level: Medium
