wireshark - several vulnerabilities

Several remote vulnerabilities have been discovered in the Wireshark
network traffic analyzer, which may lead to the execution of arbitrary

• CVE-2009-3550
  A NULL pointer dereference was found in the DCERP/NT dissector.

CVE-2009-2562,
CVE-2009-3241),
which were scheduled for the next stable point update. Also
CVE-2009-1268
was fixed for Etch. Since this security update was issued prior to the release
of the point update, the fixes were included.

version 0.99.4-5.etch.4.

For the stable distribution (lenny), this problem has been fixed in
version 1.0.2-3+lenny7.
