Wireshark, previously known as Ethereal, is a network protocol
analyzer. It is used to capture and browse the traffic running on a
Two 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.
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-2012-2392,

The wireshark packages have been upgraded to upstream version 1.8.10,
which provides a number of bug fixes and enhancements over the
previous versions. For more information on the bugs fixed,
enhancements included, and supported protocols introduced, refer to
the Wireshark Release Notes, linked to in the References. (BZ#711024)
This update also fixes the following bugs :
* Previously, Wireshark did not parse the RECLAIM-COMPLETE opcode when
inspecting traffic generated by NFSv4.1. A patch has been provided to
enable the parsing of the RECLAIM_COMPLETE opcode, and Wireshark is
now able to properly dissect and handle NFSv4.1 traffic. (BZ#750712)
* Prior to this update, frame arrival times in a text file were
reported one hour ahead from the timestamps in the packet capture
file. This resulted in various failures being reported by the
dfilter-test.py test suite. To fix this bug, frame arrival timestamps
have been shifted by one hour, thus fixing this bug. (BZ#832021)
* The 'tshark -D' command returned output to STDERR instead of STDOUT,
which could break scripts that are parsing the 'tshark -D' output.
This bug has been fixed, and the 'tshark -D' command now writes output
data to a correct standard stream. (BZ#1004636)
* Due to an array overrun, Wireshark could experience undefined
program behavior or could unexpectedly terminate. With this update,
proper array handling ensures Wireshark no longer crashes in the
described scenario. (BZ #715560)
* Previously, the dftest and randpkt command line utilities lacked
manual pages. This update adds proper manual pages for both utilities.
In addition, this update adds the following enhancements :
* With this update, Wireshark is able to properly dissect and handle
InfiniBand and GlusterFS traffic. (BZ#699636, BZ#858976)
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.
