CVE-2024-5642

一、漏洞信息
 漏洞编号：[CVE-2024-5642](https://nvd.nist.gov/vuln/detail/CVE-2024-5642)
 漏洞归属组件：[python3](https://gitee.com/src-openeuler/python3)
 漏洞归属的版本：3.10.0,3.10.2,3.10.9,3.11.1,3.11.4,3.11.6,3.7.9,3.8.5,3.9.9
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  CPython 3.9 and earlier doesn t disallow configuring an empty list ( [] ) for SSLContext.set_npn_protocols() which is an invalid value for the underlying OpenSSL API. This results in a buffer over-read when NPN is used (see CVE-2024-5535 for OpenSSL). This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice (typically a protocol name would be configured).

二、漏洞分析结构反馈
 影响性分析说明：
    CPython 3.9 及更早版本并未禁止在 SSLContext.set_npn_protocols() 中配置空列表（“【】”），而该值对于底层的 OpenSSL API 来说是无效的。当使用 NPN 时，这会导致缓冲区越界读取问题（参见 OpenSSL 的 CVE-2024-5535）。由于 NPN 并未被广泛使用，且在实际应用中配置空列表的情况也较为罕见（通常会配置协议名称），因此该漏洞的严重程度较低。
