The (1) SMB and (2) SMB2 dissectors in Wireshark 0.9.0 through 1.2.4 allow remote attackers to cause a denial of service (crash) via a crafted packet that triggers a NULL pointer dereference, as demonstrated by fuzz-2009-12-07-11141.pcap.

From Red Hat Security Advisory 2010:0360 :

Updated wireshark packages that fix several security issues are now available for Red Hat Enterprise Linux 3, 4, and 5.

The Red Hat Security Response Team has rated this update as having moderate security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section.

Wireshark is a program for monitoring network traffic. Wireshark was previously known as Ethereal.

An invalid pointer dereference flaw was found in the Wireshark SMB and SMB2 dissectors. If Wireshark read a malformed packet off a network or opened a malicious dump file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. (CVE-2009-4377)

Several buffer overflow flaws were found in the Wireshark LWRES dissector. If Wireshark read a malformed packet off a network or opened a malicious dump file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. (CVE-2010-0304)

Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, or opened a malicious dump file. (CVE-2009-2560, CVE-2009-2562, CVE-2009-2563, CVE-2009-3550, CVE-2009-3829)

Users of Wireshark should upgrade to these updated packages, which contain Wireshark version 1.0.11, and resolve these issues. All running instances of Wireshark must be restarted for the update to take effect.

Note: libsmi was added to SL4 and SL5 because it was a new dependency for wireshark and older versions of SL4 and SL5 did not have libsmi.

This update of wireshark fixes :

  - Remote attackers could potentially trigger a buffer     overflow in the Daintree SNA file parser.
    (CVE-2009-4376)

  - Specially crafted packets could cause the SMB and SMB2     dissector to crash wireshark. (CVE-2009-4377)

  - Unspecified vulnerability in the Infiniband dissector     allows remote attackers to cause a denial of service.
    (CVE-2009-2563)

  - Several buffer overflows in the LWRES dissector.
    (CVE-2010-0304)

This advisory updates wireshark to the latest 1.2.5 version, fixing several bugs and two security issues :

  - The (1) SMB and (2) SMB2 dissectors in Wireshark 0.9.0     through 1.2.4 allow remote attackers to cause a denial     of service (crash) via a crafted packet (CVE-2009-4377)

  - Buffer overflow in the daintree_sna_read function in the     Daintree SNA file parser in Wireshark 1.2.0 through     1.2.4 allows remote attackers to cause a denial of     service (crash) and possibly execute arbitrary code via     a crafted packet (CVE-2009-4376)

The remote host is affected by the vulnerability described in GLSA-201006-05 (Wireshark: Multiple vulnerabilities)

    Multiple vulnerabilities were found in the Daintree SNA file parser,     the SMB, SMB2, IPMI, and DOCSIS dissectors. For further information     please consult the CVE entries referenced below.
  Impact :

    A remote attacker could cause a Denial of Service and possibly execute     arbitrary code via crafted packets or malformed packet trace files.
  Workaround :

    There is no known workaround at this time.

The remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2010:0360 advisory.

This update of wireshark fixes :

  - CVE-2009-4376: Remote attackers could potentially     trigger a buffer overflow in the Daintree SNA file     parser.

  - CVE-2009-4377: Specially crafted packets could cause the     SMB and SMB2 dissector to crash wireshark.

  - CVE-2009-2563: Unspecified vulnerability in the     Infiniband dissector allows remote attackers to cause a     denial of service.

  - CVE-2010-0304: Several buffer overflows in the LWRES     dissector.

Several remote vulnerabilities have been discovered in the Wireshark network traffic analyzer, which may lead to the execution of arbitrary code or denial of service. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-4377     A NULL pointer dereference was found in the SMB/SMB2     dissectors.

  - CVE-2010-0304     Several buffer overflows were found in the LWRES     dissector.

This advisory updates Wireshark to the version 1.0.11, which fixes the following vulnerabilities :

The SMB and SMB2 dissectors could crash (CVE-2009-4377). The Infiniband dissector could crash on some platforms (CVE-2009-2563).
Several buffer overflows were discovered and fixed in the LWRES dissector.

Various fixes were provided in wireshark 1.2.5 - see http://www.wireshark.org/docs/relnotes/wireshark-1.2.5.html for more details. Enhancements - introduced -devel package with autoconf support - enable Lua support Fedora Bug Fixes - the root warning dialog no longer shows up The following vulnerabilities have been fixed. See the security advisory for details and a workaround.
http://www.wireshark.org/security/wnpa- sec-2009-09.html - The Daintree SNA file parser could overflow a buffer. (Bug 4294) CVE-2009-4376 - The SMB and SMB2 dissectors could crash. (Bug 4301) CVE-2009-4377 - The IPMI dissector could crash on Windows. (Bug 4319) The following bugs have been fixed: - Wireshark does not graph rtp streams. (Bug 3801) - Wireshark showing extraneous data in a TCP stream. (Bug 3955) - Wrong decoding of gtp.target identification. (Bug 3974) - TTE dissector bug. (Bug 4247) - Upper case in Lua pref symbol causes Wireshark to crash. (Bug 4255) - OpenBSD 4.5 build fails at epan/dissectors/packet-rpcap.c. (Bug 4258) - Incorrect display of stream data using 'Follow tcp stream' option. (Bug 4288) - Custom RADIUS dictionary can cause a crash. (Bug 4316) Updated Protocol Support - DAP, eDonkey, GTP, IPMI, MIP, RADIUS, RANAP, SMB, SMB2, TCP, TTE, VNC, X.509sat Updated Capture File Support - Daintree SNA.

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The installed version of Wireshark or Ethereal is potentially affected by multiple vulnerabilities :

  - The Daintree SNA file parser can overflow a buffer.
    (Bug 4294)

  - The SMB and SMB2 dissectors can crash. (Bug 4301)

  - The IPMI dissector can crash on Windows. (Bug 4319)

These vulnerabilities can result in a denial of service, or possibly arbitrary code execution.  A remote attacker can exploit these issues by tricking a user into opening a maliciously crafted capture file. Additionally, if Wireshark is running in promiscuous mode, one of these issues can be exploited remotely (from the same network segment).
