GLSA-200412-26 : ViewCVS: Information leak and XSS vulnerabilities

This script is Copyright (C) 2004-2015 Tenable Network Security, Inc.

Synopsis :

The remote Gentoo host is missing one or more security-related

Description :

The remote host is affected by the vulnerability described in GLSA-200412-26
(ViewCVS: Information leak and XSS vulnerabilities)

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.

Solution :

All ViewCVS users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose '>=www-apps/viewcvs-0.9.2_p20041207-r1'

Risk factor :

Medium / CVSS Base Score : 5.0
CVSS Temporal Score : 4.1
Public Exploit Available : true
