A flaw was found in Wireshark. A remote attacker could exploit a vulnerability in the TLS protocol dissector, which can lead to an infinite loop. This issue, triggered by processing a specially crafted TLS packet, results in a denial of service (DoS) condition, making the application unresponsive.

Mitigation for this issue is either not available or the currently available options do not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base, or stability.
