wss4j: Apache WSS4J is vulnerable to Bleichenbacher's attack (incomplete fix for CVE-2011-2487)

It was found that a prior countermeasure in Apache WSS4J for Bleichenbacher's attack on XML Encryption CVE-2011-2487 threw an exception that permitted an attacker to determine the failure of the attempted attack, thereby leaving WSS4J vulnerable to the attack. The original flaw allowed a remote...

MGASA-2016-0208 Updated botan packages fix security vulnerabilities

Updated botan packages fix security vulnerabilities: During RSA decryption, how long decoding of PKCS 1 v1.5 padding took was input dependent. If these differences could be measured by an attacker, it could be used to mount a Bleichenbacher million-message attack CVE-2015-7827. ECDSA and DSA...

MGASA-2016-0196 Updated php-ZendFramework2 packages fix CVE-2015-7503

Updated php-ZendFramework2 packages fix security vulnerability: Zend\Crypt\PublicKey\Rsa\PublicKey has a call to opensslpublicencrypt which uses PHP's default $padding argument, which specifies OPENSSLPKCS1PADDING, indicating usage of PKCS1v1.5 padding. This padding has a known vulnerability, the...

Internet Bug Bounty: Bleichenbacher oracle in SSLv2 (CVE-2016-0704)

I'm retroactively submitting CVE-2016-0704, a.k.a. "Leaky Export", which is a Bleichenbacher-style bug that leads to another variant of the Special DROWN attack. I'm submitting on behalf of myself and J. Alex Halderman, as we independently found this bug. This was validated by OpenSSL as...

Oracle MySQL 5.7.x < 5.7.12 Multiple Vulnerabilities (RPM Check) (April 2016 CPU) (July 2016 CPU) (October 2017 CPU) (DROWN)

The version of Oracle MySQL installed on the remote host is 5.7.x prior to 5.7.12. It is, therefore, affected by the following vulnerabilities : - A cipher algorithm downgrade vulnerability exists in the bundled version of OpenSSL due to a flaw that is triggered when handling cipher negotiation. ...

MySQL 5.6.x < 5.6.30 Multiple Vulnerabilities (DROWN)

The version of MySQL running on the remote host is 5.6.x prior to 5.6.30. It is, therefore, affected by multiple vulnerabilities : - A cipher algorithm downgrade vulnerability exists in the bundled version of OpenSSL due to a flaw that is triggered when handling cipher negotiation. A remote...

Amazon Linux AMI : openssl098e (ALAS-2016-682) (DROWN)

A denial of service flaw was found in the way OpenSSL handled SSLv2 handshake messages. A remote attacker could use this flaw to cause a TLS/SSL server using OpenSSL to exit on a failed assertion if it had both the SSLv2 protocol and EXPORT-grade cipher suites enabled. CVE-2015-0293 It was...
