06 Jan 2012 — The Server Gated Cryptography (SGC) implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f does not properly handle handshake restarts, which allows remote attackers to cause a denial of service (CPU consumption) via unspecified vectors. La implementación del servidor de criptografía SGC en OpenSSL antes de v0.9.8s y en v1.x antes de v1.0.0f no controla correctamente los reinicios de 'handshake' (apretón de manos), lo que permite a atacantes remotos provocar una denegación de servicio a través de vec... • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory3.asc • CWE-399: Resource Management Errors •

06 Jan 2012 — The DTLS implementation in OpenSSL before 0.9.8s and 1.x before 1.0.0f performs a MAC check only if certain padding is valid, which makes it easier for remote attackers to recover plaintext via a padding oracle attack. La implementación DTLS en OpenSSL antes de v0.9.8s y v1.x antes de v1.0.0f realiza una comprobación de MAC sólo si determinado relleno es válida, lo que facilita a los atacantes remotos a la hora de recuperar texto a través de un ataque de relleno. • http://aix.software.ibm.com/aix/efixes/security/openssl_advisory3.asc • CWE-310: Cryptographic Issues •

06 Jan 2012 — OpenSSL before 0.9.8s and 1.x before 1.0.0f, when RFC 3779 support is enabled, allows remote attackers to cause a denial of service (assertion failure) via an X.509 certificate containing certificate-extension data associated with (1) IP address blocks or (2) Autonomous System (AS) identifiers. OpenSSL antes de v0.9.8s y v1.x antes de v1.0.0f, cuando el soporte al RFC 3779 está habilitado, permite a atacantes remotos provocar una denegación de servicio (error de aserción) a través de un certificado X.509 qu... • http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c03360041 • CWE-399: Resource Management Errors •

31 May 2011 — The elliptic curve cryptography (ECC) subsystem in OpenSSL 1.0.0d and earlier, when the Elliptic Curve Digital Signature Algorithm (ECDSA) is used for the ECDHE_ECDSA cipher suite, does not properly implement curves over binary fields, which makes it easier for context-dependent attackers to determine private keys via a timing attack and a lattice calculation.

06 Dec 2010 — OpenSSL before 0.9.8j, when SSL_OP_NETSCAPE_REUSE_CIPHER_CHANGE_BUG is enabled, does not prevent modification of the ciphersuite in the session cache, which allows remote attackers to force the use of a disabled cipher via vectors involving sniffing network traffic to discover a session identifier, a different vulnerability than CVE-2010-4180.

06 Dec 2010 — OpenSSL before 1.0.0c, when J-PAKE is enabled, does not properly validate the public parameters in the J-PAKE protocol, which allows remote attackers to bypass the need for knowledge of the shared secret, and successfully authenticate, by sending crafted values in each round of the protocol.

05 Mar 2010 — The kssl_keytab_is_available function in ssl/kssl.c in OpenSSL before 0.9.8n, when Kerberos is enabled but Kerberos configuration files cannot be opened, does not check a certain return value, which allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) via SSL cipher negotiation, as demonstrated by a chroot installation of Dovecot or stunnel without Kerberos configuration files inside the chroot.
