What is CVE-2024-8645?

A vulnerability in Wireshark versions from 4.0.0 to 4.2.0 exposes the software to a denial of service risk. This issue arises from a flaw in the SPRT dissector, allowing an attacker to exploit the vulnerability through the injection of specially crafted packets or by utilizing a malicious capture file. If an affected version of Wireshark processes these inputs, it may crash, leading to disruption in service and hindering the ability to analyze network traffic effectively. Users of the affected versions should consider upgrading to a secure release to mitigate these risks. More information is available through relevant security advisories.
