Wireshark updates fix vulnerabilties
The Wireshark developers have released versions 1.4.10 and 1.6.3 of the open source, cross-platform network protocol analyser. The maintenance and security updates close multiple vulnerabilities. Some of these are rated as highly critical by Secunia, and could be exploited by an attacker to cause a denial-of-service (DoS) or compromise a victim's system.
