Note
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:
(BZ#711024)
Bug Fixes
- BZ#750712
- 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#832021
- 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#1004636
- 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#715560
- 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#659661
- Previously, the dftest and randpkt command line utilities lacked manual pages. This update adds proper manual pages for both utilities.
Enhancement
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.
