Synopsis
========

Pavuk contains a bug potentially allowing an attacker to run arbitrary
code.

Background
==========

Pavuk is web spider and website mirroring tool.

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

    -------------------------------------------------------------------
     Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
  1 net-misc/pavuk <= 0.9.28-r1 >= 0.9.28-r2

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

When Pavuk connects to a web server and the server sends back the HTTP
status code 305 (Use Proxy), Pavuk copies data from the HTTP Location
header in an unsafe manner.

Impact
======

An attacker could cause a stack-based buffer overflow which could lead
to arbitrary code execution with the rights of the user running Pavuk.

Workaround
==========

There is no known workaround at this time. All users are encouraged to
upgrade to the latest available version.

Resolution
==========

All Pavuk users should upgrade to the latest stable version:

    # emerge sync

    # emerge -pv ">=net-misc/pavuk-0.9.28-r2"
    # emerge ">="net-misc/pavuk-0.9.28-r2
