"The version of openssl installed on the remote host is prior to 1.0.2u. It is, therefore, affected by multiple
vulnerabilities as referenced in the SSA:2022-179-03 advisory.

  - 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)

  - In addition to the c_rehash shell command injection identified in CVE-2022-1292, further circumstances
    where the c_rehash script does not properly sanitise shell metacharacters to prevent command injection
    were found by code review. When the CVE-2022-1292 was fixed it was not discovered that there are other
    places in the script where the file names of certificates being hashed were possibly passed to a command
    executed through the shell. 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 3.0.4 (Affected 3.0.0,3.0.1,3.0.2,3.0.3). Fixed in
    OpenSSL 1.1.1p (Affected 1.1.1-1.1.1o). Fixed in OpenSSL 1.0.2zf (Affected 1.0.2-1.0.2ze). (CVE-2022-2068)
