Name of the Vulnerable Software and Affected Versions Wireshark versions 2.4.0 through 2.4.14 Wireshark versions 2.6.0 through 2.6.8 Wireshark versions 3.0.0 through 3.0.1

Description The issue is related to a flaw in the dissection engine of Wireshark, a network traffic analyzer, which can lead to a denial of service. This can be exploited by a remote attacker, causing the service to crash. The problem arises from insufficient control over code generation.

Recommendations For Wireshark versions 2.4.0 through 2.4.14, update to a version that restricts the number of layers and limits recursion to prevent the dissection engine from crashing. For Wireshark versions 2.6.0 through 2.6.8, update to a version that restricts the number of layers and limits recursion to prevent the dissection engine from crashing. For Wireshark versions 3.0.0 through 3.0.1, update to a version that restricts the number of layers and limits recursion to prevent the dissection engine from crashing.
