    Package        : wu-ftpd
    Vulnerability  : missing input sanitising
    Problem-Type   : remote
    Debian-specific: no
    CVE IDs        : CAN-2005-0256 CAN-2003-0854
    
    Several denial of service conditions have been discovered in wu-ftpd,
    the popular FTP daemon.  The Common Vulnerabilities and Exposures
    project identifies the following problems:
    
    CAN-2005-0256
    
        Adam Zabrocki discovered a denial of service condition in wu-ftpd
        that could be exploited by a remote user and cause the server to
        slow down the server by resource exhaustion.
    
    CAN-2003-0854
    
        Georgi Guninski discovered that /bin/ls may be called from within
        wu-ftpd in a way that will result in large memory consumption and
        hence slow down the server.
    
    For the stable distribution (woody) these problems have been fixed in
    version 2.6.2-3woody5.
    
    For the unstable distribution (sid) these problems have been fixed in
    version 2.6.2-19.
    
    We recommend that you upgrade your wu-ftpd package.
