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 ...

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...

Apple Turns on BEAST Attack Mitigation by Default in Safari

Apple enabled a feature in its recent OS X Mavericks update that neutered the BEAST cryptographic attacks. BEAST is a two-year-old attack tool that exploits a vulnerability in TLS 1.0 and SSL 3.0 and could lead to an attacker stealing HTTPS cookies or hijacking browser sessions. Apple’s Safari...

OpenSSL version rollback vulnerability

Overview OpenSSL from OpenSSL Project contains a version rollback vulnerability. If a specific option is used on a server running OpenSSL, an attacker can force the client and the server to negotiate the SSL 2.0 protocol even if these parties both request TLS 1.0 protocol by crafting an attack on...

CVE-2005-2969

The SSL/TLS server implementation in OpenSSL 0.9.7 before 0.9.7h and 0.9.8 before 0.9.8a, when using the SSLOPMSIESSLV2RSAPADDING option, disables a verification step that is required for preventing protocol version rollback attacks, which allows remote attackers to force a client and server to u...
