    Package        : lftp
    Vulnerability  : missing input validation
    Problem type   : remote (local)
    Debian-specific: no
    CVE Id         : CVE-2010-2251
    
    It was discovered that in lftp, a command-line HTTP/FTP client, there is
    no proper validation of the filename provided by the server through the
    Content-Disposition header; attackers can use this flaw by suggesting a
    filename they wish to overwrite on the client machine, and then possibly
    execute arbitrary code (for instance if the attacker elects to write a
    dotfile in a home directory).
    
    For the stable distribution (lenny), this problem has been fixed in
    version 3.7.3-1+lenny1.
    
    For the testing distribution (squeeze), this problem has been fixed in
    version 4.0.6-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.0.6-1.
    
    We recommend that you upgrade your lftp packages.
