安全公告/【CVE-2023-31130】

基本信息

漏洞名称:
受影响操作系统:Asianux
危险等级:中危
影响源码包:c-ares
CVSS评分:6.4
发现日期:2023-11-22
修复版本:c-ares-1.16.1-7

漏洞描述

c-ares is an asynchronous resolver library. ares_inet_net_pton() is vulnerable to a buffer underflow for certain ipv6 addresses, in particular "0::00:00:00/2" was found to cause an issue. C-ares only uses this function internally for configuration purposes which would require an administrator to configure such an address via ares_set_sortlist(). However, users may externally use ares_inet_net_pton() for other purposes and thus be vulnerable to more severe issues. This issue has been fixed in 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
