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"
