Description Preview

The vulnerability in Wireshark versions 2.4.0 to 2.4.4 and 2.2.0 to 2.2.12 was due to an infinite loop in the packet-reload.c file within the epan/dissectors directory. This issue was addressed by validating a length parameter to prevent the infinite loop from occurring.

Overview

This vulnerability could allow an attacker to cause a denial of service (DoS) condition by exploiting the infinite loop in the affected Wireshark versions. By sending a specially crafted packet to a vulnerable Wireshark instance, an attacker could trigger the infinite loop, leading to excessive consumption of system resources and potentially crashing the application.

Remediation

To remediate this vulnerability, users are advised to update their Wireshark installations to a version that includes the fix for the infinite loop issue. Users should upgrade to Wireshark version 2.4.5 or later for the 2.4.x branch, or version 2.2.13 or later for the 2.2.x branch. By applying the necessary updates, users can protect their systems from potential DoS attacks exploiting this vulnerability.
