OpenSSL: Multiple vulnerabilities

Background OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer SSL v2/v3 and Transport Layer Security TLS v1 as well as a general purpose cryptography library. Description Multiple vulnerabilities have been discovered in OpenSSL. Please review the CVE identifiers referenced...

Denial Of Service (DoS)

OpenSSL is vulnerable to denial of service DoS attacks. These attacks are possible when the client authentication and ephemeral Diffie-Hellman ciphersuite are enabled. They can be triggered through the use of a ClientKeyExchange with a length of zero...

Denial Of Service (DoS) Through Null Pointer Dereference

OpenSSL is vulnerable to denial of service DoS attacks through a null pointer dereference. This can be triggered at remote DTLS servers by a handshake message where the ciphersuite is specified as a 1 anonymous DH or 2 anonymous ECDH ciphersuite...

Denial Of Service (DoS) Through Null Pointer Dereference

OpenSSL is vulnerable to denial of service DoS attacks. This is caused by the sslsetclientdisabled function and triggered by a ServerHello message that includes an SRP ciphersuite but no negotiation of that suite with the client...

openssl -- multiple vulnerabilities

OpenSSL project reports: Historically OpenSSL only ever generated DH parameters based on "safe" primes. More recently in version 1.0.2 support was provided for generating X9.42 style parameter files such as those required for RFC 5114 support. The primes used in such files may not be "safe". Wher...

OpenSSL 1.0.2 < 1.0.2e Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.2e. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2e advisory. - The ASN1TFLGCOMBINE implementation in crypto/asn1/tasndec.c in OpenSSL before 0.9.8zh, 1.0.0 before 1.0.0t, 1.0.1 before 1.0.1q, a...

CVE-2015-3193

The Montgomery squaring implementation in crypto/bn/asm/x8664-mont5.pl in OpenSSL 1.0.2 before 1.0.2e on the x8664 platform, as used by the BNmodexp function, mishandles carry propagation and produces incorrect output, which makes it easier for remote attackers to obtain sensitive private-key...

openssl lib32-openssl: multiple issues

CVE-2015-3193 insecure private key in connection with DHE There is a carry propagating bug in the x8664 Montgomery squaring procedure. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not...

AIX 6.1 TL 9 : bos.net.tcp.client (U861500)

The remote host is missing AIX PTF U861500, which is related to the security of the package bos.net.tcp.client. Product could allow a remote attacker to obtain sensitive information, caused by a design error when using the SSLv3 protocol. A remote user with the ability to conduct a...
