CVE-2024-12133

一、漏洞信息
 漏洞编号：[CVE-2024-12133](https://nvd.nist.gov/vuln/detail/CVE-2024-12133)
 漏洞归属组件：[libtasn1](https://gitee.com/src-openeuler/libtasn1)
 漏洞归属的版本：4.16.0,4.17.0,4.19.0
 CVSS V3.0分值：
  BaseScore：5.3 Medium
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
 漏洞简述：
  A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate, causing a denial of service attack.
