Amazon Linux 2023:perl、perl-Attribute-Handlers、perl-AutoLoader (ALAS2023-2023-448)

critical Nessus 插件 ID 186976

简介

远程 Amazon Linux 2023 主机缺少安全更新。

描述

因此,它受到 ALAS2023-2023-448 公告中提及的多个漏洞影响。

- 在 perl 中发现一个漏洞。当 perl 编译构建的正则表达式时会出现此问题,攻击者可借此在堆栈分配缓冲区中造成受控字节缓冲区溢出。
(CVE-2023-47038)

- 在低于 5.38.2 的 Perl 中,regcomp.c 中的 S_parse_uniprop_string 可写入未分配空间,这是由于错误处理与 \p{...} 正则表达式构造相关的属性名称所致。低于 5.30.0 的版本均受影响。(CVE-2023-47100)

请注意,Nessus 尚未测试这些问题,而是只依据应用程序自我报告的版本号进行判断。

解决方案

运行“dnf update perl --releasever 2023.3.20231211”以更新系统。
