一、漏洞信息
漏洞编号：CVE-2023-5868
漏洞归属组件：libpq
漏洞归属的版本：11.16,11.2,13.12,13.13,13.7,15.0,15.4,15.5,15.6
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.
