Multiple buffer overflows in the LWRES dissector in Wireshark 0.9.15 through 1.0.10 and 1.2.0 through 1.2.5 allow remote attackers to cause a denial of service (crash) via a malformed packet, as demonstrated using a stack-based buffer overflow to the dissect_getaddrsbyname_request function.

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 update of ethereal fixes :

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

Upgrade to upstream version 1.2.6, fixing a security flaw: * http://www.wireshark.org/security/wnpa-sec-2010-02.html For full release notes, see: * http://www.wireshark.org/docs/relnotes/wireshark-1.2.6.html

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.

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.

Wireshark project reports :

Babi discovered several buffer overflows in the LWRES dissector.

It may be possible to make Wireshark crash remotely or by convincing someone to read a malformed packet trace file.

The installed version of Wireshark or Ethereal is potentially vulnerable to attack by handling data associated with the LWRES dissector. 

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.
