CVE-2019-1563
In situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker, after sending a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted...
CVE-2019-1563
CVE-2019-1563 describes a Bleichenbacher padding oracle vulnerability in OpenSSL. The issue allows an attacker, after sending a large number of ciphertexts for decryption, to recover the CMS/PKCS7 encryption key or decrypt RSA-encrypted data when the attacker can observe decryption success/failur...
Alleged 'Snake Oil' Crypto Firm Sues Over Boos at Black Hat
The paper being presented suggested that the two researchers had a method to quickly find large semiprime numbers and essentially break RSA-2048 and any other semiprime-based encryption...

CB TAU Threat Intelligence Notification: RobbinHood Ransomware Stops 181 Windows Services Before Encryption
According to source articles, RobbinHood ransomware has been discovered and it will stop 181 Windows services prior to the encryption taking place. It is thought that the ransomware might not be distributed through a typical spam campaign, but instead via other methods such as hacked remote deskt...
CVE-2018-12404
A cached side channel attack during handshakes using RSA encryption could allow for the decryption of encrypted content. This is a variant of the Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack and affects all NSS versions prior to NSS 3.41...

Side-Channel PoC Attack Lifts Private RSA Keys from Mobile Phones
Researchers have developed a proof-of-concept side-channel attack that allows them to pull encryption keys from a single decryption for a modern version of OpenSSL. The attack impacts mobile devices — without physical access to the handsets. A group of researchers at Georgia Tech were able to...
Code injection
The IKEv1 implementation in Clavister cOS Core before 11.00.11, 11.20.xx before 11.20.06, and 12.00.xx before 12.00.09 allows remote attackers to decrypt RSA-encrypted nonces by leveraging a Bleichenbacher attack...
CVE-2018-8753
CVE-2018-8753 affects the IKEv1 implementation in Clavister cOS Core (versions before 11.00.11, 11.20.xx before 11.20.06, and 12.00.xx before 12.00.09). The root cause is a Bleichenbacher RSA padding oracle that allows remote attackers to decrypt RSA-encrypted nonces during IKEv1 authentication, ...
Design/Logic Flaw
A vulnerability in the implementation of RSA-encrypted nonces in Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to obtain the encrypted nonces of an Internet Key Exchange Version 1 IKEv1 session. The vulnerability exists because the affected software...
CVE-2017-7526
libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion. The same attack is believed to work on RSA-2048 with moderately more computation. This...
