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 moderatesecurity impact. Common Vulnerability Scoring System base scores,which give detailed severity ratings, are available for each vulnerabilityfrom the CVE links in the References section. Wireshark, previously known as Ethereal, is a network protocol analyzer. Itis used to capture and browse the traffic running on a computer network.A heap-based buffer overflow flaw was found in the way Wireshark handledEndace ERF capture files. If Wireshark opened aspecially-crafted ERF capture file, it could crash or, possibly, execute arbitrary code as the user running Wireshark. Several denial of service flaws were found in Wireshark. Wireshark could crash or stop responding if it read a malformed packet off a network, oropened a malicious dump file. The CVE-2011-1958, CVE-2011-1959, CVE-2011-2175, and CVE-2011-4102 issueswere discovered by Huzaifa Sidhpurwala of the Red Hat Security ResponseTeam. This update also fixes the following bugs:* When Wireshark starts with the X11 protocol being tunneled through an SSHconnection, it automatically prepares its capture filter to omit the SSHpackets. If the SSH connection was to a link-local IPv6 address includingan interface name , Wireshark parsedthis 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 fixedand Wireshark correctly prepares a capture filter to omit SSH packets overa link-local IPv6 connection. * Previously, Wireshark's column editing dialog malformed column names when they were selected. With this update, the dialog is fixed and no longerbreaks column names. * Previously, TShark, the console packet analyzer, did not properly analyzethe exit code of Dumpcap, Wireshark's packet capturing back end. As aresult, TShark returned exit code 0 when Dumpcap failed to parse itscommand-line arguments. In this update, TShark correctly propagates theDumpcap exit code and returns a non-zero exit code when Dumpcap fails.* Previously, the TShark "-s" option worked only for avalue greater than 68 bytes. If a lower value was specified, TSharkcaptured just 68 bytes of incoming packets. With this update, the "-s"option is fixed and sizes lower than 68 bytes work as expected. This update also adds the following enhancement:* In this update, support for the "NetDump" protocol was added. 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.
