Wireshark, the world’s most popular, open-source, cross-platform, and free network protocol analyzer software, which is being used by many security experts for analysis and troubleshooting of network issues, has been updated to version 2.0.4.

Wireshark 2.0.4 is the fourth maintenance update to the 2.0 series of the application, and it comes one and a half months after the release of Wireshark 2.0.3, promising to patch a total of nine security vulnerabilities, as well as to address over 30 bugs that have been reported by the community since the previous point release.

According to the release notes, crashes have been fixed in the Toshiba file parser, CoSine file parser, NetScreen file parser, IEEE 802.11 dissector, UMTS FP dissector, Ethernet dissector, as well as some USB dissectors. The entire list of bug fixed can be studied at the end of the article, and it looks like the Windows installer now compiles with Microsoft’s Authenticode policy.

“Windows installers and PortableApps packages are dual signed using SHA-1 and SHA-256 in order to comply with Microsoft Authenticode policy. Windows 7 and Windows Server 2008 R2 users should ensure that update 3123479 is installed. Windows Vista and Windows Server 2008 users should ensure that hotfix 2763674 is installed,” reads today’s announcement.
