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

Vulnerability from cvelistv5 – Published: 2017-01-30 22:00 – Updated: 2024-08-06 02:04

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.

Severity

7.5 (High)

GHSA-6H88-QJPV-P32M

Vulnerability from github – Published: 2017-10-24 18:33 – Updated: 2022-04-25 16:33

Summary

OpenSSL gem for Ruby using inadequate encryption strength

Details

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.

Severity

7.5 (High)


                  
                    CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
