Synopsis
========

Motor uses a vulnerable ktools library, which could lead to the
execution of arbitrary code.

Background
==========

Motor is a text mode based programming environment for Linux, with a
syntax highlighting feature, project manager, makefile generator, gcc
and gdb front-end, and CVS integration.

Affected packages
=================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-util/motor lt; 3.4.0-r1 *gt;= 3.3.0-r1
gt;= 3.4.0-r1

Description
===========

In November 2005, Zone-H Research reported a boundary error in the
ktools library in the VGETSTRING() macro of kkstrtext.h, which may
cause a buffer overflow via an overly long input string.

Impact
======

A remote attacker could entice a user to use a malicious file or input,
which could lead to the crash of Motor and possibly the execution of
arbitrary code.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Motor 3.3.x users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-util/motor-3.3.0-r1"

All motor 3.4.x users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-util/motor-3.4.0-r1"
