    Synopsis
    ========
    
    A vulnerability in ProFTPD could lead to a Denial of Service condition.
    
    Background
    ==========
    
    ProFTPD is an advanced and very configurable FTP server.
    
    Affected packages
    =================
    
        -------------------------------------------------------------------
         Package              /     Vulnerable     /            Unaffected
        -------------------------------------------------------------------
      1  net-ftp/proftpd              < 1.3.7a                  >= 1.3.7a
    
    Description
    ===========
    
    It was found that ProFTPD did not properly handle invalid SCP commands.
    
    Impact
    ======
    
    An authenticated remote attacker could issue invalid SCP commands,
    possibly resulting in  a Denial of Service condition.
    
    Workaround
    ==========
    
    There is no known workaround at this time.
    
    Resolution
    ==========
    
    All ProFTPD users should upgrade to the latest version:
    
      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-ftp/proftpd-1.3.7a"
