GLSA-201612-14 : util-linux: Arbitrary code execution

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.

Synopsis :

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

Description :

The remote host is affected by the vulnerability described in GLSA-201612-14
(util-linux: Arbitrary code execution)

A command injection flaw was discovered in util-linux’s “blkid”
utility. It uses caching files (/dev/ or /run/blkid/
to store info about the UUID, LABEL etc. it finds on certain devices.
However, it does not strip ‘”’ character, so it can be confused to
build variable names containing shell metacharacters, which it would
usually encode inside the value.

Impact :

A local attacker could create a specially crafted partition label
containing arbitrary code which would get executed when the “blkid”
utility processes that value.

Workaround :

There is no known workaround at this time.

Solution :

All util-linux users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=sys-apps/util-linux-2.26'

Risk factor :

High / CVSS Base Score : 7.2
