CVE-2016-7439

CVE-2016-7439 affects the C RSA implementation in wolfSSL (formerly CyaSSL) prior to 3.9.10. The vulnerability allows a local attacker to obtain RSA keys by exploiting cache-bank hit differences, i.e., an information-disclosure issue. Affected products/versions are wolfSSL before 3.9.10; impact i...

CVE-2016-7440

The C software implementation of AES Encryption and Decryption in wolfSSL formerly CyaSSL before 3.9.10 makes it easier for local users to discover AES keys by leveraging cache-bank timing differences...

FreeBSD : FreeBSD -- Multiple OpenSSL vulnerabilities (7b1a4a27-600a-11e6-a6c3-14dae9d210b8) (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: Side channel attack on modular exponentiation

A side-channel attack was found that makes use of cache-bank conflicts on the Intel Sandy-Bridge microarchitecture. An attacker who has the ability to control code in a thread running on the same hyper-threaded core as the victim's thread that is performing decryption, could use this flaw to...

Scientific Linux Security Update : openssl on SL6.x, SL7.x i386/x86_64 (20160301) (DROWN)

A padding oracle flaw was found in the Secure Sockets Layer version 2.0 SSLv2 protocol. An attacker can potentially use this flaw to decrypt RSA-encrypted cipher text from a connection using a newer SSL/TLS protocol version, allowing them to decrypt such connections. This cross-protocol attack is...
