DoS (Denial of Service)
This includes vulnerabilities ranging from excessive resource consumption (e.g. causing a system to use a lot of memory) to crashing an application or an entire system.
Two vulnerabilities have been reported in Wireshark, which can be exploited by malicious people to cause a DoS (Denial of Service).
1) An error within the PPP dissector can be exploited to cause a crash via a specially crafted packet.
2) An error within the NFS dissector can be exploited to consume CPU resources and cause a crash via a specially crafted packet.
The vulnerabilities are reported in versions prior to 1.8.1, 1.6.9, and 1.4.14.
Update to version 1.8.1, 1.6.9, or 1.4.14.
