Description

According to the versions of the sssd packages installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- A flaw was found in SSSD, where the sssctl command was vulnerable to shell command injection via the logs- fetch and cache-expire subcommands. This flaw allows an attacker to trick the root user into running a specially crafted sssctl command, such as via sudo, to gain root access. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability. (CVE-2021-3621)
