CVE-2025-4516

一、漏洞信息
 漏洞编号：[CVE-2025-4516](https://nvd.nist.gov/vuln/detail/CVE-2025-4516)
 漏洞归属组件：[python3](https://gitee.com/src-openeuler/python3)
 漏洞归属的版本：3.10.2,3.10.9,3.11.11,3.11.4,3.11.6,3.7.9,3.8.5,3.9.9
 CVSS V3.0分值：
  BaseScore：N/A None
  Vector：CVSS：3.0/
 漏洞简述：
  There is an issue in CPython when using `bytes.decode( unicode_escape , error= ignore|replace )`. If you are not using the  unicode_escape  encoding or an error handler your usage is not affected. To work-around this issue you may stop using the error= handler and instead wrap the bytes.decode() call in a try-except catching the DecodeError.

二、漏洞分析结构反馈
 影响性分析说明：
  在CPython中使用`bytes.decode（ unicode_escape ,error= 忽略|替换 ）`时有一个问题。如果您没有使用unicode_escape编码或错误处理程序，则您的使用不会受到影响。要解决此问题，您可以停止使用error=处理程序，而是将bytes.decode()调用包装在try中，除非捕获DecodeError。
