Title

Botan弱加密漏洞

Description

Botan是一个C++的加密算法库，它支持AES、DES、SHA-1、RSA、DSA和Diffie-Hellman等多种算法。 Botan 1.10.8之前版本和1.11.9之前1.11.x版本的Miller-Rabin素性检验中存在弱加密漏洞，该漏洞源于程序未能正确使用单一的随机基数。远程攻击者可利用该漏洞借助DH组破坏加密保护机制。

CVE-2014-9742 (GCVE-0-2014-9742)

Vulnerability from cvelistv5 – Published: 2016-05-13 14:00 – Updated: 2024-08-06 13:55

Summary

The Miller-Rabin primality check in Botan before 1.10.8 and 1.11.x before 1.11.9 improperly uses a single random base, which makes it easier for remote attackers to defeat cryptographic protection mechanisms via a DH group.

Severity

No CVSS data available.
