Oracle Linux 9：libvirt (ELSA-2024-2560)
medium Nessus 插件 ID 195125
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 9 主机上安装的程序包受到 ELSA-2024-2560 公告中提及的多个漏洞的影响。- 在 libvirt 的 RPC 库 API 中发现一个缺陷。RPC 服务器反序列化代码在 C API 入口点执行非负长度检查之前为数组分配内存。将负长度传递到 g_new0 函数会导致崩溃，这是由于负长度被视为巨大正数所导致的。本地非特权用户可利用此缺陷，导致 libvirt 后台程序崩溃，从而执行拒绝服务攻击。(CVE-2024-2494)
- 据发现，当接口数量超过“names”数组的大小时，libvirt 的 udevListInterfacesByStatus() 函数中存在差一错误缺陷。此问题可通过将特别构建的数据发送到 libvirt 后台程序来重现，从而允许非特权客户端通过造成 libvirt 后台程序崩溃来执行拒绝服务攻击。(CVE-2024-1441)
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。
