简介

远程 Ubuntu 主机缺少一个或多个安全更新。

描述

远程 Ubuntu 20.04 LTS / 21.04 主机上安装的程序包受到 USN-5113-1 公告中提及的多个漏洞的影响。

- 在 5.13.13 之前版本的 Linux 内核中,drivers/net/hamradio/6pack.c 中的 decode_data 函数存在 slab 越界写入漏洞。具有 CAP_NET_ADMIN 功能的进程提供的输入可能导致 root 访问。
(CVE-2021-42008)

- 在 APQ8053、IPQ4019、IPQ8064、MSM8909W、MSM8996AU、QCA9531、QCN5502、QCS405、SDX20、SM6150、SM7150 中,使用特别定时和手动构建的流量可在 WLAN 设备中造成内部错误,导致第 2 层 Wi-Fi 加密不当,从而可能导致 Snapdragon Auto、Snapdragon Compute、Snapdragon Connectivity、Snapdragon Consumer IOT、Snapdragon Industrial IOT、Snapdragon Mobile、Snapdragon Voice & Music、Snapdragon Wearables 和 Snapdragon Wired Infrastructure and Networking 中一组离散流量的信息在传送中泄漏 (CVE-2020-3702)

- 在 Linux 内核 5.13.8 及之前版本中,如果将许多元素置于单个存储桶中,则 kernel/bpf/hashtab.c 中存在整数溢出和越界写入。注意:在不使用 CAP_SYS_ADMIN 功能的情况下,可能无法利用此漏洞。(CVE-2021-38166)

- 在 Linux 内核 5.13.13 及之前版本的 ext4 子系统中,在 fs/ext4/inline.c 中的 ext4_write_inline_data_end 中发现一个争用条件 。(CVE-2021-40490)

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。
