7.230. wireshark

Updated wireshark packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.
Red Hat Product Security 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, which is used to capture and browse the traffic running on a computer network.

Security Fix

CVE-2014-8714, CVE-2014-8712, CVE-2014-8713, CVE-2014-8711, CVE-2014-8710, CVE-2015-0562, CVE-2015-0564, CVE-2015-2189, CVE-2015-2191
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.

Bug Fixes

BZ#1095065
Previously, the Wireshark tool did not support Advanced Encryption Standard Galois/Counter Mode (AES-GCM) cryptographic algorithm. As a consequence, AES-GCM was not decrypted. Support for AES-GCM has been added to Wireshark, and AES-GCM is now correctly decrypted.
BZ#1121275
Previously, when installing the system using the kickstart method, a dependency on the shadow-utils packages was missing from the wireshark packages, which could cause the installation to fail with a "bad scriptlet" error message. With this update, shadow-utils are listed as required in the wireshark packages spec file, and kickstart installation no longer fails.
BZ#1131203
Prior to this update, the Wireshark tool could not decode types of elliptic curves in Datagram Transport Layer Security (DTLS) Client Hello. Consequently, Wireshark incorrectly displayed elliptic curves types as data. A patch has been applied to address this bug, and Wireshark now decodes elliptic curves types properly.
BZ#1160388
Previously, a dependency on the gtk2 packages was missing from the wireshark packages. As a consequence, the Wireshark tool failed to start under certain circumstances due to an unresolved symbol, "gtk_combo_box_text_new_with_entry", which was added in gtk version 2.24. With this update, a dependency on gtk2 has been added, and Wireshark now always starts as expected.

Enhancements

BZ#1104210
With this update, the Wireshark tool supports process substitution, which feeds the output of a process (or processes) into the standard input of another process using the "<(command_list)" syntax. When using process substitution with large files as input, Wireshark failed to decode such input.
BZ#1146578
Wireshark has been enhanced to enable capturing packets with nanosecond time stamp precision, which allows better analysis of recorded network traffic.
All wireshark users are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. All running instances of Wireshark must be restarted for the update to take effect.
