Synopsis
========

An out-of-bounds data access in minicom might allow remote attackers to
execute arbitrary code.

Background
==========

Minicom is a text-based serial port communications program.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-dialup/minicom < 2.7.1 >= 2.7.1

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

In minicom before version 2.7.1, the escparms[] buffer in vt100.c is
vulnerable to an overflow.

Impact
======

A remote attacker, able to connect to a minicom port, could possibly
execute arbitrary code with the privileges of the process, or cause a
Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All minicom users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dialup/minicom-2.7.1"
