(monkeyd: Multiple vulnerabilities)

    Tavis Ormandy of the Gentoo Linux Security Audit Team discovered a
    double expansion error in monkeyd, resulting in a format string
    vulnerability. Ciaran McCreesh of Gentoo Linux discovered a Denial of
    Service vulnerability, a syntax error caused monkeyd to zero out
    unallocated memory should a zero byte file be requested.
  
Impact :

    The format string vulnerability could allow an attacker to send a
    specially crafted request to the monkeyd server, resulting in the
    execution of arbitrary code with the permissions of the user running
    monkeyd. The DoS vulnerability could allow an attacker to disrupt the
    operation of the web server, should a zero byte file be accessible.
  
Workaround :

    There is no known workaround at this time."
