OpenSSL DTLS implementation code execution

openssl-dtls-code-execution (37185)

High Risk

Description:

OpenSSL could allow a remote attacker to execute arbitrary code on the system, caused by an unspecified error in the DTLS implementation. If DTLS is enabled on the clients and servers, an attacker could crash the application or execute arbitrary code on the vulnerable system.
