CVE-2023-5868

一、漏洞信息
 漏洞编号：[CVE-2023-5868](https://nvd.nist.gov/vuln/detail/CVE-2023-5868)
 漏洞归属组件：[libpq](https://gitee.com/src-openeuler/libpq)
 漏洞归属的版本：11.16,11.2,13.12,13.13,13.17,13.7,15.0,15.4,15.5,15.6,15.9
 CVSS V3.0分值：
  BaseScore：4.3 Medium
  Vector：CVSS：3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
 漏洞简述：
  A memory disclosure vulnerability was found in PostgreSQL that allows remote users to access sensitive information by exploiting certain aggregate function calls with  unknown -type arguments. Handling  unknown -type values from string literals without type designation can disclose bytes, potentially revealing notable and confidential information. This issue exists due to excessive data output in aggregate function calls, enabling remote users to read some portion of system memory.

二、漏洞分析结构反馈
 影响性分析说明：
  Certain aggregate function calls receiving  unknown -type arguments could disclose bytes of server memory from the end of the  unknown -type value to the next zero byte. One typically gets an  unknown -type value via a string literal having no type designation. We have not confirmed or ruled out viability of attacks that arrange for presence of notable, confidential information in disclosed bytes.
