Synopsis
=======

ViewCVS is vulnerable to an information leak and to cross-site scripting (XSS) issues.

Background
=========

ViewCVS is a browser interface for viewing CVS and Subversion version control repositories through a web browser.

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

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 www-apps/viewcvs <= 0.9.2_p20041207 >= 0.9.2_p20041207-r1

Description
==========

The tar export functions in ViewCVS bypass the 'hide_cvsroot' and 'forbidden' settings and therefore expose information that should be kept secret (CAN-2004-0915). Furthermore, some error messages in ViewCVS do not filter user-provided information, making it vulnerable to a cross-site scripting attack (CAN-2004-1062).

Impact
=====

By using the tar export functions, a remote attacker could access information that is configured as restricted. Through the use of a malicious request, an attacker could also inject and execute malicious script code, potentially compromising another user's browser.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All ViewCVS users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose
">=www-apps/viewcvs-0.9.2_p20041207-r1"
