Synopsis
========

Pavuk contains multiple buffer overflows that can allow a remote
attacker to run arbitrary code.

Background
==========

Pavuk is web spider and website mirroring tool.

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

     -------------------------------------------------------------------
      Package         /  Vulnerable  /                       Unaffected
     -------------------------------------------------------------------
   1  net-misc/pavuk      < 0.9.31                            >= 0.9.31

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

Pavuk contains several buffer overflow vulnerabilities in the code
handling digest authentication and HTTP header processing. This issue
is similar to GLSA 200407-19, but contains more vulnerabilities.

Impact
======

A remote attacker could cause a buffer overflow, leading to arbitrary
code execution with the rights of the user running Pavuk.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Pavuk users should upgrade to the latest version:

     # emerge --sync
     # emerge --ask --oneshot --verbose ">=net-misc/pavuk-0.9.31"
