"The remote Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the
RLSA-2022:5818 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)

  - AES OCB mode for 32-bit x86 platforms using the AES-NI assembly optimised implementation will not encrypt
    the entirety of the data under some circumstances. This could reveal sixteen bytes of data that was
    preexisting in the memory that wasn't written. In the special case of in place encryption, sixteen bytes
    of the plaintext would be revealed. Since OpenSSL does not support OCB based cipher suites for TLS and
    DTLS, they are both unaffected. Fixed in OpenSSL 3.0.5 (Affected 3.0.0-3.0.4). Fixed in OpenSSL 1.1.1q
    (Affected 1.1.1-1.1.1p). (CVE-2022-2097)
