The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2022:1766 advisory.

  - LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual     aids that no alteration of the document occurred since the last signing and that the signature is valid.
    An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to create a digitally     signed ODF document, by manipulating the documentsignatures.xml or macrosignatures.xml stream within the     document to combine multiple certificate data, which when opened caused LibreOffice to display a validly     signed indicator but whose content was unrelated to the signature shown. This issue affects: The Document     Foundation LibreOffice 7-0 versions prior to 7.0.6; 7-1 versions prior to 7.1.2. (CVE-2021-25633)

  - LibreOffice supports digital signatures of ODF documents and macros within documents, presenting visual     aids that no alteration of the document occurred since the last signing and that the signature is valid.
    An Improper Certificate Validation vulnerability in LibreOffice allowed an attacker to modify a digitally     signed ODF document to insert an additional signing time timestamp which LibreOffice would incorrectly     present as a valid signature signed at the bogus signing time. This issue affects: The Document Foundation     LibreOffice 7-0 versions prior to 7.0.6; 7-1 versions prior to 7.1.2. (CVE-2021-25634)
