CherryPy is a Python-based, object-oriented web development framework.
Ivo van der Wijk discovered that the "staticfilter" component of CherryPy fails to sanitize input correctly.
An attacker could exploit this flaw to obtain arbitrary files from the web server.
There is no known workaround at this time.
All CherryPy users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-python/cherrypy-2.1.1"
