Ubuntu 16.04 LTS / 18.04 LTS:Linux 内核漏洞 (USN-5209-1)

high Nessus 插件 ID 156484

简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 16.04 LTS/18.04 LTS 主机上安装的程序包受到 USN-5209-1 公告中提及的多个漏洞的影响。

- 在 5.14.12 之前版本的 Linux 内核中,kernel/bpf/stackmap.c 中的 prealloc_elems_and_freelist 允许非特权用户触发 eBPF 乘法整数溢出,从而导致越界写入。(CVE-2021-41864)

- Linux 内核中发现缺陷。NFC 堆栈中存在一个释放后使用漏洞,可对机密性、完整性和系统可用性造成威胁。(CVE-2021-3760)

- Linux 内核中发现缺陷。定时器树损坏,导致 lib/timerqueue.c 的 timerqueue_add 函数中缺少任务唤醒。此缺陷使拥有特殊用户特权的本地攻击者能够造成拒绝服务,从而在运行 OSP 期间导致系统的运行速度变慢并最终停止系统。
(CVE-2021-20317)

- 在用户使用 OverlayFS 以特定方式重命名的方式中,发现访问 Linux 内核 OverlayFS 子系统中的文件对象时存在争用条件。本地用户可利用此缺陷导致系统崩溃。
(CVE-2021-20321)

- 在 Linux 内核 5.14.15 之前的版本中发现问题。drivers/isdn/capi/kcapi.c 的 detach_capi_ctr 函数中存在 array-index-out-of-bounds 缺陷。(CVE-2021-43389)

请注意,Nessus 尚未测试此问题,而是只依靠应用程序自我报告的版本号来判断。
