安全公告/【CVE-2023-31124】

基本信息

漏洞名称:
受影响操作系统:Asianux
危险等级:低危
影响源码包:c-ares
CVSS评分:3.7
发现日期:2023-08-31
修复版本:c-ares-1.16.1-7

漏洞描述

c-ares is an asynchronous resolver library. When cross-compiling c-ares and using the autotools build system, CARES_RANDOM_FILE will not be set, as seen when cross compiling aarch64 android. This will downgrade to using rand() as a fallback which could allow an attacker to take advantage of the lack of entropy by not using a CSPRNG. This issue was patched in version 1.19.1.

修复方式

yum update PackageName

漏洞判定

执行命令yum info PackageName获取软件包版本号，版本小于修复版本，则受此漏洞影响，版本大于等于修复版本，则此漏洞已修复
