Synopsis
========

A vulnerability in libsoup might allow remote attackers to execute
arbitrary code.

Background
==========

libsoup is an HTTP client/server library for GNOME.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-libs/libsoup             < 2.56.1                  >= 2.56.1 

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

A stack based buffer overflow vulnerability was discovered in libsoup.

Impact
======

A remote attacker, by using specially crafted HTTP requests, could
execute arbitrary code with the privileges of the process.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All libsoup users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-libs/libsoup-2.56.1"
