OVERVIEW

        A number of vulnerabilities have been identified in Wireshark prior
        to versions 1.4.13 and 1.6.8.


IMPACT

        The vendor has provided the following details regarding these
        vulnerabilities:
        
        "Infinite and large loops in the ANSI MAP, ASF, BACapp, Bluetooth HCI, 
        IEEE 802.11, IEEE 802.3, LTP, and R3 dissectors have been fixed.
        Discovered by Laurent Butti. 
        
        It may be possible to make Wireshark hang for long or indefinite 
        periods by injecting a malformed packet onto the wire or by convincing 
        someone to read a malformed packet trace file." [1]
        
        "The DIAMETER dissector could try to allocate memory improperly and 
        crash. 
        
        It may be possible to make Wireshark crash by injecting a malformed
        packet onto the wire or by convincing someone to read a malformed
        packet trace file." [2]
        
        "Wireshark could crash on SPARC or Itanium processors due to 
        misaligned memory. Discovered by Klaus Heckelmann. 
        
        It may be possible to make Wireshark crash by injecting a malformed 
        packet onto the wire or by convincing someone to read a malformed 
        packet trace file." [3]


MITIGATION

        The vendor recommends updating to the latest versions of Wireshark
        to correct these issues. [1, 2, 3]
