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"
