      "value": "A vulnerability was determined in seladb PcapPlusPlus 25.05. The impacted element is the function pcpp::SSLClientHelloMessage::getHandshakeVersion of the file Packet++/src/SSLHandshake.cpp of the component TLS Hello Handler. Executing a manipulation of the argument handshakeVersion can lead to heap-based buffer overflow. It is possible to launch the attack remotely. This attack is characterized by high complexity. The exploitability is regarded as difficult. The exploit has been publicly disclosed and may be utilized. This patch is called 98e671010bc7c87b95898c22ae289220ae92542b. It is best practice to apply a patch to resolve this issue."
