high Nessus 插件 ID 149822
语言：
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。
