Synopsis
========

There is a heap-based buffer overflow vulnerability in the neon library
used in cadaver, possibly leading to execution of arbitrary code when
connected to a malicious server.

Background
==========

cadaver is a command-line WebDAV client.

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

    -------------------------------------------------------------------
     Package           /   Vulnerable   /                   Unaffected

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

Stefan Esser discovered a vulnerability in the code of the neon library
(see GLSA 200405-13). This library is also included in cadaver.

Impact
======

When connected to a malicious WebDAV server, this vulnerability could
allow remote execution of arbitrary code with the rights of the user
running cadaver.

Workaround
==========

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

Resolution
==========

All users of cadaver should upgrade to the latest stable version:

    # emerge sync
