New version of Wireshark fixes vulnerabilities in the PPP and NFS dissectors

(LiveHacking.Com) – Versions 1.6.9 and 1.8.1 of Wireshark, the open source network protocol analyzer, have been released to address two vulnerabilities that could be exploited by a remote attacker to cause a denial of service (DoS).

The first problem is a crash in the PPP dissector. It is possible to make Wireshark crash by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. Versions affected are 1.4.0 to 1.4.13, 1.6.0 to 1.6.8, 1.8.0.

The other vulnerability in the NFS dissector can cause excessive amounts of CPU. It is possible to provoke the condition by injecting a malformed packet onto the wire or by convincing someone to read a malformed packet trace file. Versions affected are 1.4.0 to 1.4.13, 1.6.0 to 1.6.8, 1.8.0.

Upgrading to 1.6.9 or 1.8.1 fixes both problems. More information (including a full list of known issues and changes) can be found in the 1.6.9 and 1.8.1 release notes. Wireshark 1.6.9 and 1.8.1 are available to download  for Windows, Mac OS X 10.5.5 and above (Intel and PPC). The source code is also available.

Wireshark Version 1.6.0 released

The Wireshark development team has released Wireshark version 1.6.0 of its open source, cross-platform network protocol analyzer.

This new version of Wireshark improves support for large files and has some new features such as the ability to export SSL session keys and SMB objects. The users can now import text dumps into Wireshark and TShark, similar to text2pcap. Further, TShark can now display iSCSI, ICMP and ICMPv6 service response times.

Wireshark is now distributed as an installation package rather than a drag-installer on OS X. The installer adds a startup item that should make it easier to capture packets. Please visit Wireshark version 1.6.0 release notes for a complete list of changes.

The H Security: Scope of DLL security problem widens – Update

After HD Moore released details last week about the DLL problem under Windows, along with a testing tool, an increasing number of affected applications and their matching exploits have been reported. In addition to Firefox and Opera, vulnerable programs include such popular applications as PowerPoint, Photoshop, Dreamweaver, VLC, uTorrent and Wireshark – in each case, the current version is affected. They all use an insecure way of loading DLLs in which at an early stage the search order contains the current directory – a directory that could be on a network device.
