1.7 sthen 115: An incorrectly formatted ClientHello handshake message could cause
116: OpenSSL to parse past the end of the message. An attacker could use this flaw
117: to trigger an invalid memory access, causing a crash of an application linked

124: in v2.3.3; this is newer than the version in ports.
