    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 :

    There is no known workaround at this time."
