"Several vulnerabilities were discovered upstream in ethereal, a
network traffic analyzer. The Common Vulnerabilities and Exposures
project identifies the following problems :

  - CAN-2003-0925
    A buffer overflow allows remote attackers to cause a
    denial of service and possibly execute arbitrary code
    via a malformed GTP MSISDN string.

  - CAN-2003-0926

    Via certain malformed ISAKMP or MEGACO packets remote
    attackers are able to cause a denial of service (crash).

  - CAN-2003-0927

    A heap-based buffer overflow allows remote attackers to
    cause a denial of service (crash) and possibly execute
    arbitrary code via the SOCKS dissector.

  - CAN-2003-1012

    The SMB dissector allows remote attackers to cause a
    denial of service via a malformed SMB packet that
    triggers a segmentation fault during processing of
    selected packets.

  - CAN-2003-1013

    The Q.931 dissector allows remote attackers to cause a
    denial of service (crash) via a malformed Q.931, which
    triggers a null dereference."
