CVE-2016-7798 (GCVE-0-2016-7798)

Vulnerability from cvelistv5

Published

2017-01-30 22:00

Modified

2024-08-06 02:04

Severity ?

CWE

Summary

The openssl gem for Ruby uses the same initialization vector (IV) in GCM Mode (aes-*-gcm) when the IV is set before the key, which makes it easier for context-dependent attackers to bypass the encryption protection mechanism.
