Wireshark is the world’s most popular network protocol analyzer. It is used for troubleshooting, analysis, development and education.
The following vulnerabilities have been fixed:
Prior to this release dumpcap enabled the Linux kernel’s BPF JIT
compiler via the
net.core.bpf_jit_enable sysctl. This could make
systems more vulnerable to Spectre variant 1 (CVE-2017-5753)
and this feature has been removed (Bug 14313).
The following bugs have been fixed:
- First start with non-empty extcap folder after install or reboot hangs at "initializing tap listeners". (Bug 12845)
- SIP Statistics extract does not work. (Bug 13942)
- Service Response Time - SCSI dialog crashes. (Bug 14144)
- SOCKS pseudo header displays incorrect Version value. (Bug 14262)
- Only first variable of list is dissected in NTP Control request message. (Bug 14268)
- NTP Authenticator field dissection fails if padding is used. (Bug 14269)

- Saving a temporary capture file may not result in the temporary file being removed. (Bug 14298)
There are no new or updated capture interfaces supported in this release.
Wireshark source code and installation packages are available from https://www.wireshark.org/download.html.
Most Linux and Unix vendors supply their own Wireshark packages. You can usually install or upgrade Wireshark using the package management system specific to that platform. A list of third-party packages can be found on the download page on the Wireshark web site.
Wireshark and TShark look in several different locations for preference files, plugins, SNMP MIBS, and RADIUS dictionaries. These locations vary from platform to platform. You can use About→Folders to find the default locations on your system.
Dumpcap might not quit if Wireshark or TShark crashes. (Bug 1419)

Capture filters aren’t applied when capturing from named pipes. (Bug 1814)
Filtering tshark captures with read filters (-R) no longer works. (Bug 2234)
Application crash when changing real-time option. (Bug 4035)
Wireshark and TShark will display incorrect delta times in some cases. (Bug 4985)
