Synopsis
=3D=3D=3D=3D=3D=3D=3D=3D

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

Background
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

sudo (su =E2=80=9Cdo=E2=80=9D) allows a system administrator to delegate au=
thority 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
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 app-admin/sudo < 1.8.20_p2 >=3D
1.8.20_p2=20

Description
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

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
=3D=3D=3D=3D=3D=3D

A local attacker could execute arbitrary code with root privileges.

Workaround
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

There is no known workaround at this time.

Resolution
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D

All sudo users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=3Dapp-admin/sudo-1.8.20_p2"
