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

  - The c_rehash script does not properly sanitise shell metacharacters to prevent command injection. This
    script is distributed by some operating systems in a manner where it is automatically executed. On such
    operating systems, an attacker could execute arbitrary commands with the privileges of the script. Use of
    the c_rehash script is considered obsolete and should be replaced by the OpenSSL rehash command line tool.
    Fixed in OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2). Fixed in OpenSSL 1.1.1o (Affected 1.1.1-1.1.1n).
    Fixed in OpenSSL 1.0.2ze (Affected 1.0.2-1.0.2zd). (CVE-2022-1292)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security
advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional
issues.");
