Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED12 / SLED_SAP12 / SLES12 / SLES_SAP12 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:1093-1 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.

Solution

Update the affected packages.
