Oracle Linux 6:perl (ELSA-2021-9238)

high Nessus 插件 ID 149822

简介

远程 Oracle Linux 主机缺少一个或多个安全更新。

描述

远程 Oracle Linux 6 主机上安装的程序包受到 ELSA-2021-9238 公告中提及的多个漏洞的影响。

- 在 32 位平台上,5.30.3 之前的 Perl 允许基于堆的缓冲区溢出,这是因为嵌套正则表达式的量词存在一个整数溢出漏洞。(CVE-2020-10543)

- 5.30.3 之前的 Perl 存在一个整数溢出漏洞,该漏洞与 PL_regkind[OP(n)] == NOTHING 状况处理不当有关。构建的正则表达式可导致畸形字节码,并且可能会注入指令。(CVE-2020-10878)

- 在 5.30.3 之前的 Perl 中,regcomp.c 可通过构建的正则表达式造成缓冲区溢出,这是因为递归 S_study_chunk 调用。(CVE-2020-12723)

请注意,Nessus 尚未测试此问题,而是只依赖于应用程序自我报告的版本号。
