Synopsis
========

Multiple vulnerabilities in WebSVN allow for file overwrite and
information disclosure.

Background
==========

WebSVN is a web-based browsing tool for Subversion repositories written
in PHP.

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

    -------------------------------------------------------------------
     Package          /  Vulnerable  /                      Unaffected
    -------------------------------------------------------------------
  1  www-apps/websvn       < 2.1.0                            >= 2.1.0

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

* James Bercegay of GulfTech Security reported a Cross-site scripting
  (XSS) vulnerability in the getParameterisedSelfUrl() function in
  index.php (CVE-2008-5918) and a directory traversal vulnerability in
  rss.php when magic_quotes_gpc is disabled (CVE-2008-5919).

* Bas van Schaik reported that listing.php does not properly enforce
  access restrictions when using an SVN authz file to authenticate
  users (CVE-2009-0240).

Impact
======

A remote attacker can exploit these vulnerabilities to overwrite
arbitrary files, to read changelogs or diffs for restricted projects
and to hijack a user's session.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All WebSVN users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=www-apps/websvn-2.1.0"
