    Package        : wu-ftpd
    Vulnerability  : insecure program execution
    Problem-Type   : remote
    Debian-specific: no
    CVE Ids        : CVE-1999-0997
    
    wu-ftpd, an FTP server, implements a feature whereby multiple files
    can be fetched in the form of a dynamically constructed archive file,
    such as a tar archive.  The names of the files to be included are
    passed as command line arguments to tar, without protection against
    them being interpreted as command-line options.  GNU tar supports
    several command line options which can be abused, by means of this
    vulnerability, to execute arbitrary programs with the privileges of
    the wu-ftpd process.
    
    Georgi Guninski pointed out that this vulnerability exists in Debian
    woody.
    
    For the stable distribution (woody) this problem has been fixed in
    version 2.6.2-3woody2.
    
    For the unstable distribution (sid) this problem will be fixed soon.
    
    We recommend that you update your wu-ftpd package.
    
    Upgrade Instructions
