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 Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - Heap-based buffer overflow in the erf_read_header function in wiretap/erf.c in the ERF file parser in     Wireshark 1.4.0 through 1.4.9 and 1.6.x before 1.6.3 allows remote attackers to cause a denial of service     (application crash) via a malformed file. (CVE-2011-4102)

Note that Nessus relies on the presence of the package as reported by the vendor.

Updated wireshark packages that fix several security issues, three bugs, and add one enhancement are now available for Red Hat Enterprise Linux 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, previously known as Ethereal, is a network protocol analyzer. It is used to capture and browse the traffic running on a computer network.

A heap-based buffer overflow flaw was found in the way Wireshark handled Endace ERF (Extensible Record Format) capture files. If Wireshark opened a specially crafted ERF capture file, it could crash or, possibly, execute arbitrary code as the user running Wireshark.
(CVE-2011-4102)

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-2011-1958, CVE-2011-1959, CVE-2011-2175, CVE-2011-2698, CVE-2012-0041, CVE-2012-0042, CVE-2012-0066, CVE-2012-0067, CVE-2012-4285, CVE-2012-4289, CVE-2012-4290, CVE-2012-4291)

The CVE-2011-1958, CVE-2011-1959, CVE-2011-2175, and CVE-2011-4102 issues were discovered by Huzaifa Sidhpurwala of the Red Hat Security Response Team.

This update also fixes the following bugs :

* When Wireshark starts with the X11 protocol being tunneled through an SSH connection, it automatically prepares its capture filter to omit the SSH packets. If the SSH connection was to a link-local IPv6 address including an interface name (for example ssh -X [ipv6addr]%eth0), Wireshark parsed this address erroneously, constructed an incorrect capture filter and refused to capture packets. The 'Invalid capture filter' message was displayed. With this update, parsing of link-local IPv6 addresses is fixed and Wireshark correctly prepares a capture filter to omit SSH packets over a link-local IPv6 connection. (BZ#438473)

* Previously, Wireshark's column editing dialog malformed column names when they were selected. With this update, the dialog is fixed and no longer breaks column names. (BZ#493693)

* Previously, TShark, the console packet analyzer, did not properly analyze the exit code of Dumpcap, Wireshark's packet capturing back end. As a result, TShark returned exit code 0 when Dumpcap failed to parse its command-line arguments. In this update, TShark correctly propagates the Dumpcap exit code and returns a non-zero exit code when Dumpcap fails. (BZ#580510)

* Previously, the TShark '-s' (snapshot length) option worked only for a value greater than 68 bytes. If a lower value was specified, TShark captured just 68 bytes of incoming packets. With this update, the '-s' option is fixed and sizes lower than 68 bytes work as expected.
(BZ#580513)

This update also adds the following enhancement :

* In this update, support for the 'NetDump' protocol was added.
(BZ#484999)

All users of Wireshark are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add this enhancement. All running instances of Wireshark must be restarted for the update to take effect.

The installed version of Wireshark is 1.4.x before 1.4.10.  This version is affected by the following vulnerabilities :

  - An error exists in the Infiniband dissector that can     allow a NULL pointer to be dereferenced when processing     certain malformed packets. (CVE-2011-4101)

  - A buffer overflow exists in the ERF file reader and can     be triggered when processing certain malformed packets.
    (CVE-2011-4102)

The installed version of Wireshark is 1.6.x before 1.6.3.  This version is affected by the following vulnerabilities :

  - An error exists in CSN.1 dissector that can allow denial     of service attacks when processing certain malformed     packets. (CVE-2011-4100)

  - An error exists in the Infiniband dissector that can     allow a NULL pointer to be dereferenced when processing     certain malformed packets. (CVE-2011-4101)

  - A buffer overflow exists in the ERF file reader and can     be triggered when processing certain malformed packets.
    (CVE-2011-4102)

Huzaifa Sidhpurwala discovered a buffer overflow in Wireshark's ERF dissector, which could lead to the execution of arbitrary code.

Tenable has extracted the preceding description block directly from the Oracle Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

This advisory updates wireshark to the latest version (1.6.3), fixing several security issues :

An uninitialized variable in the CSN.1 dissector could cause a crash (CVE-2011-4100).

Huzaifa Sidhpurwala of Red Hat Security Response Team discovered that the Infiniband dissector could dereference a NULL pointer (CVE-2011-4101).

Huzaifa Sidhpurwala of Red Hat Security Response Team discovered a buffer overflow in the ERF file reader (CVE-2011-4102).

The updated packages have been upgraded to the latest 1.6.x version (1.6.3) which is not vulnerable to these issues.
