    Update
    ======

    While working on the tcpdump issues solved in the original version of
    this GLSA, Simon L. Nielsen from FreeBSD Security Team discovered a
    similar infinite loop DoS vulnerability in the BGP handling code
    (CAN-2005-1267). New packages have been released to address this new
    issue.

    The updated sections appear below.

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

        -------------------------------------------------------------------
         Package / Vulnerable / Unaffected
        -------------------------------------------------------------------
      1 net-analyzer/tcpdump < 3.8.3-r3 >= 3.8.3-r3

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

    TCPDump improperly handles and decodes ISIS (CAN-2005-1278), BGP
    (CAN-2005-1267, CAN-2005-1279), LDP (CAN-2005-1279) and RSVP
    (CAN-2005-1280) packets. TCPDump might loop endlessly after receiving
    malformed packets.

    Resolution
    ==========

    All TCPDump users should upgrade to the latest available version:

        # emerge --sync
        # emerge --ask --oneshot --verbose ">=net-analyzer/tcpdump-3.8.3-r3"
