Juniper Junos Multiple OpenSSL Vulnerabilities (JSA10759) (SWEET32)

According to its self-reported version number, the remote Juniper Junos device is affected by the following vulnerabilities related to OpenSSL : - A flaw exists in the ssl3getkeyexchange function in file s3clnt.c when handling a ServerKeyExchange message for an anonymous DH ciphersuite with the...

Juniper ScreenOS 6.3.x < 6.3.0r23 Multiple Vulnerabilities in OpenSSL (JSA10759) (DROWN)

The version of Juniper ScreenOS running on the remote host is 6.3.x prior to 6.3.0r23. It is, therefore, affected by multiple vulnerabilities in its bundled version of OpenSSL : - A flaw exists in the SSLv2 implementation, specifically in the getclientmasterkey function within file s2srvr.c, due ...

Jose-php Information Disclosure Vulnerability

jose-php is suitable for PHP JSON object signature and encryption library . A security vulnerability exists in versions of jose-php before 2.2.1, due to the lack of a random padding mechanism in the implementation of the RSA 1.5 algorithm in the JWE.php/JOSEJWE class. A remote attacker can obtain...

Cross-protocol attack on TLS using SSLv2 (DROWN) (CVE-2016-0800)

现在流行的服务器和客户端使用TLS加密, 然而由于错误配置, 许多服务器仍然支持SSLv2, 这是一种古老的协议, 许多客户端已经不支持 SSLv2。 DROWN攻击可以威胁到还在支持 SSLv2 的服务端和客户端,允许攻击者通过发送 probe 到支持 SSLv2 的使用相同密钥的服务端和客户端解密 TLS 通信。 官方关于漏洞的公告: A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and...

CVE-2016-0703

CVE-2016-0703 concerns OpenSSL SSLv2: the get_client_master_key function in s2_srvr.c accepts a nonzero CLIENT-MASTER-KEY CLEAR-KEY-LENGTH for arbitrary ciphers, enabling Bleichenbacher-style padding oracle exploitation to recover the MASTER-KEY and decrypt TLS traffic. Public sources attribute t...

CVE-2016-0800 & CVE-2016-0703 OpenSSL vulnerabilities | Cloud Foundry

CVE-2016-0800 & CVE-2016-0703 OpenSSL vulnerabilities High Vendor OpenSSL Versions Affected SSLv2 Description The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possess...

CVE-2016-0800

The SSLv2 protocol, as used in OpenSSL before 1.0.1s and 1.0.2 before 1.0.2g and other products, requires a server to send a ServerVerify message before establishing that a client possesses certain plaintext RSA data, which makes it easier for remote attackers to decrypt TLS ciphertext data by...

Vulnerability in OpenSSL - Cross-protocol attack on TLS using SSLv2 (DROWN)

A cross-protocol attack was discovered that could lead to decryption of TLS sessions by using a server supporting SSLv2 and EXPORT cipher suites as a Bleichenbacher RSA padding oracle. Note that traffic between clients and non-vulnerable servers can be decrypted provided another server supporting...

OpenSSL 1.0.2 < 1.0.2a Multiple Vulnerabilities

The version of OpenSSL installed on the remote host is prior to 1.0.2a. It is, therefore, affected by multiple vulnerabilities as referenced in the 1.0.2a advisory. - An oracle protection mechanism in the getclientmasterkey function in s2srvr.c in the SSLv2 implementation in OpenSSL before 0.9.8z...

jbossws: Prone to Bleichenbacher attack against to be distributed symmetric key

A flaw was found in JBoss web services where the services used a weak symmetric encryption protocol, PKCS1 v1.5. An attacker could use this weakness in chosen-ciphertext attacks to recover the symmetric key and conduct further attacks...

FreeBSD : FreeBSD -- OpenSSL multiple vulnerabilities (2ae114de-c064-11e1-b5e0-000c299b62e1)

Problem description : OpenSSL fails to clear the bytes used as block cipher padding in SSL 3.0 records when operating as a client or a server that accept SSL 3.0 handshakes. As a result, in each record, up to 15 bytes of uninitialized memory may be sent, encrypted, to the SSL peer. This could...
