Multiple serious vulnerabilities have been found in Wireshark. Malicious users can exploit these vulnerabilities to cause a denial of service.

Below is a complete list of vulnerabilities:

1. Multiple unspecified vulnerabilities in the AMQP and MQ dissectors can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to read a specially designed packet trace file to cause a denial of service;
2. An infinite loop in the DOCSIS dissector can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to handle a specially designed packet trace file to cause a denial of service;
3. An unspecified vulnerability in the openSAFETY dissector can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to handle a specially designed packet trace file to cause a denial of service;
4. An infinite loop in the WXML dissector can be exploited remotely via a specially designed packet, which is injected onto the wire, or by convincing a user to handle a specially designed packet trace file to cause a denial of service.

Technical details

For vulnerabilities (1) and (2), denial of service is a crash.

Vulnerabilities (1) are related to epan/dissectors/packet-mq.c and epan/dissectors/packet-amqp.c.

Denial of service, which might become a result of exploiting vulnerabilities (2) and (4), occurs because of consuming excessive CPU resources.

In case of vulnerability (3), denial of service can be a crash or a system memory exhaustion.

Vulnerabilities (3) is related plugins/docsis/packet-docsis.c.
