CVE-2016-7798

CVE-2016-7798 affects the Ruby OpenSSL OpenSSL gem. The issue is incorrect handling of the IV in GCM mode when the IV is set before the key, enabling context-dependent attackers to bypass encryption protection. The connected advisories indicate fixed/upgraded versions in various distributions (e....

Ruby: Ruby OpenSSL Library - IV Reuse in GCM Mode

Hello, An IV reuse bug was discovered in Ruby's OpenSSL library when using aes-gcm. When encrypting data with aes--gcm, if the IV is set before setting the key, the cipher will default to using a static IV. This creates a static nonce and since aes-gcm is a stream cipher, this can lead to known...
