Gentoo Linux Security Advisory

Title: sudo: Privilege escalation (GLSA 201710-04)
Severity: high
Exploitable: local
Date: 2017-10-08
Bug(s): #620482
ID: 201710-04

Synopsis

A vulnerability in sudo allows local users to gain root privileges.

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.


Affected Packages

Package: app-admin/sudo
Vulnerable: < 1.8.20_p2
Unaffected: >= 1.8.20_p2
Architectures: All supported architectures


Description

The fix present in app-admin/sudo-1.8.20_p1 (GLSA 201705-15) was
incomplete as it did not address the problem of a command with a newline
in the name.


Impact

A local attacker could execute arbitrary code with root privileges.

Workaround

There is no known workaround at this time.

Resolution

All sudo users should upgrade to the latest version:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.8.20_p2"
