Gentoo Linux Security Advisory
Title: ViewCVS: Information leak and XSS vulnerabilities (GLSA 200412-26)
Severity: low
Exploitable: remote
Date: December 28, 2004
Bug(s): #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: www-apps/viewcvs
Vulnerable: <= 0.9.2_p20041207
Unaffected: >= 0.9.2_p20041207-r1
Architectures: All supported architectures
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: Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=www-apps/viewcvs-0.9.2_p20041207-r1" |
