Background
Wireshark is a network protocol analyzer that allows users to capture and analyze network traffic. It is widely used by network administrators and security professionals for troubleshooting and monitoring purposes. Wireshark supports a wide range of protocols and provides detailed information about network packets. However, several vulnerabilities have been discovered in Wireshark that could lead to denial of service or the execution of arbitrary code.
Vulnerability Detail
The vulnerabilities in Wireshark affect the dissectors for CIP Safety, IWARP_MPA, NetBIOS, Profinet I/O, and AMQP. These vulnerabilities could be exploited by an attacker to cause a denial of service or execute arbitrary code on a vulnerable system. The specific details of each vulnerability are as follows:
- CIP Safety Dissector: This vulnerability could be triggered by a specially crafted packet and may result in a crash or arbitrary code execution.
- IWARP_MPA Dissector: A remote attacker could exploit this vulnerability by sending a specially crafted packet, leading to a crash or potential code execution.
- NetBIOS Dissector: An attacker could exploit this vulnerability by sending a specially crafted packet, resulting in a denial of service or arbitrary code execution.
- Profinet I/O Dissector: This vulnerability could be triggered by a specially crafted packet and may result in a crash or arbitrary code execution.
- AMQP Dissector: A remote attacker could exploit this vulnerability by sending a specially crafted packet, leading to a crash or potential code execution.
