(gFTP: Multiple vulnerabilities)

    Kalle Olavi Niemitalo discovered two boundary errors in fsplib code
    included in gFTP when processing overly long directory or file names.
  
Impact :

    A remote attacker could trigger these vulnerabilities by enticing a
    user to download a file with a specially crafted directory or file
    name, possibly resulting in the execution of arbitrary code
    (CVE-2007-3962) or a Denial of Service (CVE-2007-3961).
  
Workaround :

    There is no known workaround at this time."
