OpenSSL AES-NI Padding Oracle MitM Information Disclosure Low Nessus Plugin ID 91572. Synopsis It was possible to obtain sensitive information from the remote host May 04, 2016 · On May 3, 2016, the OpenSSL Software Foundation released a security advisory that included six vulnerabilities. Of the six vulnerabilities disclosed, four of them may cause memory corruption or excessive memory usage, one could allow a padding oracle attack to decrypt traffic when the connection uses an AES CBC cipher and the server supports AES-NI, and, lastly, one is specific to a product To check whether or not AES NI is enabled check the contents of /proc/crypto $ grep module /proc/crypto | sort -u module : aesni_intel module : aes_x86_64 module : arc4 module : kernel To see if OpenSSL supports AES-NI run openssl engine Major changes between OpenSSL 1.0.2g and OpenSSL 1.0.2h [3 May 2016] Prevent padding oracle in AES-NI CBC MAC check (CVE-2016-2107) Fix EVP_EncodeUpdate overflow (CVE-2016-2105) Fix EVP_EncryptUpdate overflow (CVE-2016-2106) Prevent ASN.1 BIO excessive memory allocation (CVE-2016-2109) EBCDIC overread (CVE-2016-2176) Apache Commons Crypto is a cryptographic library optimized with AES-NI (Advanced Encryption Standard New Instructions). It provides Java API for both cipher level and Java stream level. Developers can use it to implement high performance AES encryption/decryption with the minimum code and effort. Oct 16, 2018 · The AES-NI support is a great improvement, as all recent x86 CPUs support for it. Using it, the performance of the encrypted channel is greatly improved. The LibreSSL library has support for AES-NI, so you only need to enable it (and if it's enabled, but not supported by the hardware, then the software implementation is used). Apr 28, 2016 · Quoting form the draft of OpenSSL upstream advisory: Padding oracle in AES-NI CBC MAC check (CVE-2016-2107) ===== Severity: High A MITM attacker can use a padding oracle attack to decrypt traffic when the connection uses an AES CBC cipher and the server support AES-NI.

Why Intel® AES-NI Matters. Encryption is frequently recommended as the best way to secure business-critical data, and AES is the most widely used standard when protecting network traffic, personal data, and corporate IT infrastructures.

Sep 03, 2015 · On Intel some OpenSSH ciphers use hardware accelerated AES-NI extensions which leads to significally better performance. There is a pretty easy way to determine cipher performance on any particular Linux installation:
