The installed version of Wireshark is 1.6.x before 1.6.6.  This version is affected by the following vulnerabilities :

 - An error exists in the pcap and pcap-ng parsers that    can allow them to crash when reading 'ERF' data.
   (Issue 6804)

 - An error exists in the IEEE 802.11 dissector that can    cause it to go into an infinite loop. (Issue 6809)

 - An error exists in the 'ANSI A' dissector that can allow    it to crash after dereferencing a NULL pointer.
   (Issue 6823)

 - An error exists in the 'MP2T' dissector that can allow    it to allocate too much memory thus resulting in    crashes. (Issue 6833)

This version upgrade of wireshark fixes the following security vulnerabilities :

  - The ANSI A dissector could dereference a NULL pointer     and crash. (CVE-2012-1593)

  - The pcap and pcap-ng file parsers could crash trying to     read ERF data. (CVE-2012-1595)

  - The MP2T dissector could try to allocate too much memory     and crash. (CVE-2012-1596) Additionally, various other     non-security bugs have been fixed.

Updated wireshark packages that fix several security issues are now available for Red Hat Enterprise Linux 6.

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.

Several flaws were found in Wireshark. 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-2011-1590, CVE-2011-4102, CVE-2012-1595)

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-2011-1143, CVE-2011-1957, CVE-2011-1958, CVE-2011-1959, CVE-2011-2174, CVE-2011-2175, CVE-2011-2597, CVE-2011-2698, CVE-2012-0041, CVE-2012-0042, CVE-2012-0067, CVE-2012-0066)

Users of Wireshark should upgrade to these updated packages, which contain backported patches to correct these issues. All running instances of Wireshark must be restarted for the update to take effect.

The following vulnerabilities have been fixed. wnpa-sec-2012-04: The ANSI A dissector could dereference a NULL pointer and crash. (Bug 6823)

wnpa-sec-2012-06: The pcap and pcap-ng file parsers could crash trying to read ERF data. (Bug 6804)

wnpa-sec-2012-07: The MP2T dissector could try to allocate too much memory and crash. (Bug 6833)

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 is 1.4.x before 1.4.12.  This version is affected by the following vulnerabilities :

The remote Solaris system is missing necessary patches to address security updates :

  - epan/dissectors/packet-ansi_a.c in the ANSI A dissector     in Wireshark 1.4.x before 1.4.12 and 1.6.x before 1.6.6     allows remote attackers to cause a denial of service     (NULL pointer dereference and application crash) via a     malformed packet. (CVE-2012-1593)

  - epan/dissectors/packet-ieee80211.c in the IEEE 802.11     dissector in Wireshark 1.6.x before 1.6.6 allows remote     attackers to cause a denial of service (infinite loop)     via a crafted packet. (CVE-2012-1594)

  - The pcap_process_pseudo_header function in     wiretap/pcap-common.c in Wireshark 1.4.x before 1.4.12     and 1.6.x before 1.6.6 allows remote attackers to cause     a denial of service (application crash) via a     WTAP_ENCAP_ERF file containing an Extension or     Multi-Channel header with an invalid pseudoheader size,     related to the pcap and pcap-ng file parsers.
    (CVE-2012-1595)

  - The mp2t_process_fragmented_payload function in     epan/dissectors/packet-mp2t.c in the MP2T dissector in     Wireshark 1.4.x before 1.4.12 and 1.6.x before 1.6.6     allows remote attackers to cause a denial of service     (application crash) via a packet containing an invalid     pointer value that triggers an incorrect     memory-allocation attempt. (CVE-2012-1596)

Multiple vulnerabilities was found and corrected in Wireshark :

  - The ANSI A dissector could dereference a NULL pointer     and crash.

    - The IEEE 802.11 dissector could go into an infinite       loop.

    - The pcap and pcap-ng file parsers could crash trying       to read ERF data.

  - The MP2T dissector could try to allocate too much memory     and crash.

This advisory provides the latest version of Wireshark (1.6.6) which is not vulnerable to these issues.
