06 Aug 2014 — The ssl23_get_client_hello function in s23_srvr.c in OpenSSL 1.0.1 before 1.0.1i allows man-in-the-middle attackers to force the use of TLS 1.0 by triggering ClientHello message fragmentation in communication between a client and server that both support later TLS versions, related to a "protocol downgrade" issue. La función ssl23_get_client_hello en s23_srvr.c en OpenSSL 1.0.1 anterior a 1.0.1i permite a atacantes man-in-the-middle forzar el uso de TLS 1.0 mediante la provocación de la fragmentación de men... • ftp://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2014-008.txt.asc • CWE-390: Detection of Error Condition Without Action •

05 Jun 2014 — OpenSSL before 0.9.8za, 1.0.0 before 1.0.0m, and 1.0.1 before 1.0.1h does not properly restrict processing of ChangeCipherSpec messages, which allows man-in-the-middle attackers to trigger use of a zero-length master key in certain OpenSSL-to-OpenSSL communications, and consequently hijack sessions or obtain sensitive information, via a crafted TLS handshake, aka the "CCS Injection" vulnerability.
