openssl: TLS protocol downgrade attack

A flaw was found in the way OpenSSL handled fragmented handshake packets. A man-in-the-middle attacker could use this flaw to force a TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client and the server supported newer protocol versions...

CVE-2014-3511

The ssl23getclienthello function in s23srvr.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...

CVE-2014-3511

CVE-2014-3511 affects OpenSSL 1.0.1 (and related 1.0.0/1.0.1 branches) where the ssl23_get_client_hello path (s23_srvr.c) can be triggered to fragment a ClientHello and force downgrading to TLS 1.0 when both client and server support later TLS versions. This enables a man-in-the-middle to induce ...

MGASA-2014-0325 Updated openssl packages fix security vulnerabilities

A flaw in OBJobj2txt may cause pretty printing functions such as X509nameoneline, X509nameprintex et al. to leak some information from the stack. Applications may be affected if they echo pretty printing output to the attacker. OpenSSL SSL/TLS clients and servers themselves are not affected...

OpenSSL 1.0.1 < 1.0.1i Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.1i. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.1i advisory. - The sslsetclientdisabled function in t1lib.c in OpenSSL 1.0.1 before 1.0.1i allows remote SSL servers to cause a denial of service...

USN-2308-1 openssl vulnerabilities

Adam Langley and Wan-Teh Chang discovered that OpenSSL incorrectly handled certain DTLS packets. A remote attacker could use this issue to cause OpenSSL to crash, resulting in a denial of service. CVE-2014-3505 Adam Langley discovered that OpenSSL incorrectly handled memory when processing DTLS...
