Description Preview
The vulnerability in Wireshark versions 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12 is due to an infinite loop in the packet-rpki-rtr.c file. This issue was addressed by validating a length field to prevent the loop from occurring.
Overview
This vulnerability in Wireshark could be exploited by an attacker to cause a denial of service by triggering the infinite loop condition. By sending a specially crafted packet to a vulnerable Wireshark instance, an attacker could potentially crash the application or consume excessive resources, leading to a disruption in network monitoring and analysis.
Remediation
To remediate this vulnerability, users are advised to update their Wireshark installations to versions that have addressed the issue. Users should upgrade to Wireshark versions beyond 2.4.4 or 2.2.12, where the validation of the length field has been implemented to prevent the infinite loop from occurring.
