ViewVC is a browser interface for CVS and Subversion version control repositories.
Multiple unspecified errors were reportedly fixed by the ViewVC development team.
A remote attacker could send a specially crafted URL to the server to list CVS or SVN commits on "all-forbidden" files, access hidden CVSROOT folders, and view restricted content via the revision view, the log history, or the diff view.
There is no known workaround at this time.
All ViewVC users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=www-apps/viewvc-1.0.5"
