Date: December 28, 2004
Bugs: #72461, #73772
ID: 200412-26

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-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"
