一、漏洞信息
 漏洞编号：[CVE-2023-44271](https://nvd.nist.gov/vuln/detail/CVE-2023-44271)
 漏洞归属组件：[python-pillow](https://gitee.com/src-openeuler/python-pillow)
 漏洞归属的版本：10.0.0,5.3.0,7.2.0,8.1.1,8.1.2,9.0.1,9.3.0,9.5.0
 CVSS V3.0分值：
  BaseScore：7.5 High
  Vector：CVSS：3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
 漏洞简述：
  An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.

二、漏洞分析结构反馈
 影响性分析说明：
    在 10.0.0 之前的 Pillow 中发现了一个问题。这是一种拒绝服务，它会不受控制地分配内存来处理给定的任务，可能会因内存不足而导致服务崩溃。当 ImageDraw 实例中的 textlength 对长文本参数进行操作时，ImageFont 中的 truetype 会发生这种情况。
