Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Linux/Unix 主机中安装的一个或多个程序包受到一个漏洞影响，而供应商没有提供补丁程序。

  - Clam AntiVirus (ClamAV) 1.4.0版、 1.3.2 和先前版本、所有 1.2.x 版、 1.0.6 和先前版本、所有 0.105.x 版、所有 0.104.x 版以及 0.103.11 和所有版本的 ClamD 服务模块中存在漏洞之前的版本可允许经身份验证的本地攻击者损坏关键的系统文件。该漏洞是由于允许 ClamD 进程在有特权的情况下写入其日志文件，而未检查日志文件是否已替换为符号链接而造成的。如果攻击者将 ClamD 日志文件替换为重要系统文件的符号链接并找到重新启动 ClamD 进程的方法，则可能利用此漏洞。若成功利用该漏洞，攻击者则可通过在重新启动后附加 ClamD 日志消息来损坏重要系统文件。(CVE-2024-20506)

请注意，Nessus 依赖供应商报告的程序包是否存在进行判断。

远程 Azure Linux 3.0 主机上安装的 clamav 版本低于 测试的版本。因此，该程序受到 CVE-2024-20506 公告中提及的一个漏洞影响。
