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 contain both "X509Data" and "KeyValue" children of the "KeyInfo" tag, which when opened caused LibreOffice to verify using the "KeyValue" but to report verification with the unrelated "X509Data" value. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.5.

The remote Redhat Enterprise Linux 8 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - libreoffice: Incorrect trust validation of signature with ambiguous KeyInfo children (CVE-2021-25636)

  - libreoffice: Empty entry in Java class path (CVE-2022-38745)

  - 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)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

The remote Rocky Linux 8 host has packages installed that are affected by a vulnerability as referenced in the RLSA-2022:7461 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 contain both X509Data and KeyValue children of the KeyInfo tag, which when opened caused     LibreOffice to verify using the KeyValue but to report verification with the unrelated X509Data value.
    This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.5. (CVE-2021-25636)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3368 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 contain both X509Data and KeyValue children of the KeyInfo tag, which when opened caused     LibreOffice to verify using the KeyValue but to report verification with the unrelated X509Data value.
    This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.5. (CVE-2021-25636)

  - An Improper Certificate Validation vulnerability in LibreOffice existed where determining if a macro was     signed by a trusted author was done by only matching the serial number and issuer string of the used     certificate with that of a trusted certificate. This is not sufficient to verify that the macro was     actually signed with the certificate. An adversary could therefore create an arbitrary certificate with a     serial number and an issuer string identical to a trusted certificate which LibreOffice would present as     belonging to the trusted author, potentially leading to the user to execute arbitrary code contained in     macros improperly trusted. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to     7.2.7; 7.3 versions prior to 7.3.1. (CVE-2022-26305)

  - LibreOffice supports the storage of passwords for web connections in the user's configuration database.
    The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice     existed where the required initialization vector for encryption was always the same which weakens the     security of the encryption making them vulnerable if an attacker has access to the user's configuration     data. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions     prior to 7.3.1. (CVE-2022-26306)

  - LibreOffice supports the storage of passwords for web connections in the user's configuration database.
    The stored passwords are encrypted with a single master key provided by the user. A flaw in LibreOffice     existed where master key was poorly encoded resulting in weakening its entropy from 128 to 43 bits making     the stored passwords vulerable to a brute force attack if an attacker has access to the users stored     config. This issue affects: The Document Foundation LibreOffice 7.2 versions prior to 7.2.7; 7.3 versions     prior to 7.3.3. (CVE-2022-26307)

  - LibreOffice supports Office URI Schemes to enable browser integration of LibreOffice with MS SharePoint     server. An additional scheme 'vnd.libreoffice.command' specific to LibreOffice was added. In the affected     versions of LibreOffice links using that scheme could be constructed to call internal macros with     arbitrary arguments. Which when clicked on, or activated by document events, could result in arbitrary     script execution without warning. This issue affects: The Document Foundation LibreOffice 7.4 versions     prior to 7.4.1; 7.3 versions prior to 7.3.6. (CVE-2022-3140)
