GLSA 201706-13: minicom: Remote execution of arbitrary code

Severity:normal
Title:minicom: Remote execution of arbitrary code
Date:06/06/2017
Bugs: #615996
ID:201706-13

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 Architecture(s)
net-dialup/minicom < 2.7.1 >= 2.7.1 All supported architectures

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"
