This advisory updates wireshark to the latest version (1.2.16),
fixing several security issues:

The X.509if dissector in Wireshark 1.2.x before 1.2.16 and 1.4.x
before 1.4.5 does not properly initialize certain global variables,
which allows remote attackers to cause a denial of service (application
crash) via a crafted .pcap file (CVE-2011-1590).

Stack-based buffer overflow in the DECT dissector in
epan/dissectors/packet-dect.c in Wireshark 1.4.x before 1.4.5 allows
remote attackers to execute arbitrary code via a crafted .pcap file
(CVE-2011-1591).

The NFS dissector in epan/dissectors/packet-nfs.c in Wireshark 1.4.x
before 1.4.5 on Windows uses an incorrect integer data type during
decoding of SETCLIENTID calls, which allows remote attackers to cause
a denial of service (application crash) via a crafted .pcap file
(CVE-2011-1592).

The updated packages have been upgraded to the latest 1.2.x version
(1.2.16) which is not vulnerable to these issues.
