    Package        : libreoffice     Version        : 1:6.1.5-3+deb10u8     CVE ID         : CVE-2021-25636 CVE-2022-3140 CVE-2022-26305 CVE-2022-26306                      CVE-2022-26307

    Multiple vulnerabilities were found in LibreOffice an     office productivity software suite, leading to arbitrary script     execution, improper certificate validation, and weak encryption     of password storage in the user??s configuration database.

    CVE-2021-25636

        Only use X509Data         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.

    CVE-2022-3140

        Insufficient validation of vnd.libreoffice.command         URI schemes. 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.

    CVE-2022-26305

        Compare authors using Thumbprint         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.

    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 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

    CVE-2022-26307

        Add Initialization Vectors to password storage.
        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.

    For Debian 10 buster, these problems have been fixed in version     1:6.1.5-3+deb10u8.

    We recommend that you upgrade your libreoffice packages.
