The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:3602-1 advisory.

  - 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 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)

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