=====================================================================

1. Summary:

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.

2. Relevant releases/architectures:

RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, ppc, s390x, x86_64
Red Hat Enterprise Linux Desktop (v. 5 client) - i386, x86_64

3. Description:

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.

4. Solution:

Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
