Background

Cherokee is an extra-light web server.

Description
==========
Florian Schilhabel from the Gentoo Linux Security Audit Team found a
format string vulnerability in the cherokee_logger_ncsa_write_string()
function.

Impact

Using a specially crafted URL when authenticating via auth_pam, a
malicious user may be able to crash the server or execute arbitrary
code on the target machine with permissions of the user running
Cherokee.

Workaround
