KLA11034 Multiple vulnerabilities in Wireshark

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

Below is a complete list of vulnerabilities:

1. An improper handling of dividing by zero in the L2CAP 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;
2. Multiple unspecified vulnerabilities in the MSNIP, RGMP, IPv6 dissectors 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 DICOM 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;
5. Infinite loops in the DNS, SoulSeek and Bazaar dissectors 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;
6. An out-of-bounds read in the DHCP and DOF dissectors 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;
7. A null pointer dereference in the ROS 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

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