    Synopsis
    ========

    A vulnerability has been discovered in ProFTPd which could result in
    memory disclosure.

    Background
    ==========

    ProFTPD is an advanced and very configurable FTP server.

    Affected packages
    =================

    -------------------------------------------------------------------
    Package / Vulnerable / Unaffected
    -------------------------------------------------------------------
    1 net-ftp/proftpd < 1.3.7c >= 1.3.7c

    Description
    ===========

    ProFTPd unconditionally sends passwords to Radius servers for
    authentication in multiples of 16 bytes. If a password is not of a
    length that is a multiple of 16 bytes, ProFTPd will read beyond the end
    of the password string and send bytes beyond the end of the string
    buffer.

    Impact
    ======

    Radius servers used for authentication can receive the contents of the
    ProFTPd process' memory.

    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-1.3.7c"

    References
    ==========
