CVE-2024-28834

一、漏洞信息
 漏洞编号：[CVE-2024-28834](https://nvd.nist.gov/vuln/detail/CVE-2024-28834)
 漏洞归属组件：[gnutls](https://gitee.com/src-openeuler/gnutls)
 漏洞归属的版本：3.6.14,3.6.15,3.7.2,3.7.8,3.8.0
 CVSS V2.0分值：
  BaseScore：0.0 Low
  Vector：CVSS：2.0/
 漏洞简述：
  A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.

二、漏洞分析结构反馈
 影响性分析说明：
              在GnuTLS中发现了一个漏洞。Minerva攻击是一种加密漏洞，利用类似GnuTLS的系统中的确定性行为，导致侧信道泄漏。在特定情况下，例如使用GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE标志时，它可能导致nonce大小从513位到512位的明显步骤，从而暴露潜在的时间侧信道。
