Synopsis
========

A buffer overflow in socat might allow remote attackers to execute
arbitrary code.

Background
==========

socat is a multipurpose bidirectional relay, similar to netcat.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-misc/socat              < 1.7.2.1                 >= 1.7.2.1

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

A vulnerability in the "xioscan_readline()" function in xio-readline.c
could cause a heap-based buffer overflow.

Impact
======

A remote attacker could possibly execute arbitrary code with the
privileges of the socat process.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All socat users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-misc/socat-1.7.2.1"
