According to the versions of the libreoffice packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - libreoffice: Arbitrary python functions in arbitrary     modules on the filesystem can be executed without     warning (CVE-2018-16858)

  - LibreOffice has a feature where documents can specify     that pre-installed scripts can be executed on various     document events such as mouse-over, etc. LibreOffice is     typically also bundled with LibreLogo, a programmable     turtle vector graphics script, which can be manipulated     into executing arbitrary python commands. By using the     document event feature to trigger LibreLogo to execute     python contained within a document a malicious document     could be constructed which would execute arbitrary     python commands silently without warning. In the fixed     versions, LibreLogo cannot be called from a document     event handler. This issue affects: Document Foundation     LibreOffice versions prior to 6.2.5.(CVE-2019-9848)

  - LibreOffice is typically bundled with LibreLogo, a     programmable turtle vector graphics script, which can     execute arbitrary python commands contained with the     document it is launched from. LibreOffice also has a     feature where documents can specify that pre-installed     scripts can be executed on various document script     events such as mouse-over, etc. Protection was added,     to address CVE-2019-9848, to block calling LibreLogo     from script event handers. However an insufficient url     validation vulnerability in LibreOffice allowed     malicious to bypass that protection and again trigger     calling LibreLogo from script event handlers. This     issue affects: Document Foundation LibreOffice versions     prior to 6.2.6.(CVE-2019-9850)

  - LibreOffice is typically bundled with LibreLogo, a     programmable turtle vector graphics script, which can     execute arbitrary python commands contained with the     document it is launched from. Protection was added, to     address CVE-2019-9848, to block calling LibreLogo from     document event script handers, e.g. mouse over. However     LibreOffice also has a separate feature where documents     can specify that pre-installed scripts can be executed     on various global script events such as document-open,     etc. In the fixed versions, global script event     handlers are validated equivalently to document script     event handlers. This issue affects: Document Foundation     LibreOffice versions prior to 6.2.6.(CVE-2019-9851)

  - LibreOffice has a feature where documents can specify     that pre-installed macros can be executed on various     script events such as mouse-over, document-open etc.
    Access is intended to be restricted to scripts under     the share/Scripts/python, user/Scripts/python     sub-directories of the LibreOffice install. Protection     was added, to address CVE-2018-16858, to avoid a     directory traversal attack where scripts in arbitrary     locations on the file system could be executed. However     this new protection could be bypassed by a URL encoding     attack. In the fixed versions, the parsed url     describing the script location is correctly encoded     before further processing. This issue affects: Document     Foundation LibreOffice versions prior to     6.2.6.(CVE-2019-9852)

The remote CentOS Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2020:1151 advisory.

  - LibreOffice has a feature where documents can specify that pre-installed scripts can be executed on     various document events such as mouse-over, etc. LibreOffice is typically also bundled with LibreLogo, a     programmable turtle vector graphics script, which can be manipulated into executing arbitrary python     commands. By using the document event feature to trigger LibreLogo to execute python contained within a     document a malicious document could be constructed which would execute arbitrary python commands silently     without warning. In the fixed versions, LibreLogo cannot be called from a document event handler. This     issue affects: Document Foundation LibreOffice versions prior to 6.2.5. (CVE-2019-9848)

  - LibreOffice has a 'stealth mode' in which only documents from locations deemed 'trusted' are allowed to     retrieve remote resources. This mode is not the default mode, but can be enabled by users who want to     disable LibreOffice's ability to include remote resources within a document. A flaw existed where bullet     graphics were omitted from this protection prior to version 6.2.5. This issue affects: Document Foundation     LibreOffice versions prior to 6.2.5. (CVE-2019-9849)

  - LibreOffice is typically bundled with LibreLogo, a programmable turtle vector graphics script, which can     execute arbitrary python commands contained with the document it is launched from.

This issue affects: Document Foundation LibreOffice versions prior to 6.2.6.
    (CVE-2019-9852)

  - LibreOffice documents can contain macros. The execution of those macros is controlled by the document     security settings, typically execution of macros are blocked by default. A URL decoding flaw existed in     how the urls to the macros within the document were processed and categorized, resulting in the     possibility to construct a document where macro execution bypassed the security settings. The documents     were correctly detected as containing macros, and prompted the user to their existence within the     documents, but macros within the document were subsequently not controlled by the security settings     allowing arbitrary macro execution This issue affects: LibreOffice 6.2 series versions prior to 6.2.7;
    LibreOffice 6.3 series versions prior to 6.3.1. (CVE-2019-9853)

  - LibreOffice has a feature where documents can specify that pre-installed macros can be executed on various     script events such as mouse-over, document-open etc. Access is intended to be restricted to scripts under     the share/Scripts/python, user/Scripts/python sub-directories of the LibreOffice install. Protection was     added, to address CVE-2019-9852, to avoid a directory traversal attack where scripts in arbitrary     locations on the file system could be executed by employing a URL encoding attack to defeat the path     verification step. However this protection could be bypassed by taking advantage of a flaw in how     LibreOffice assembled the final script URL location directly from components of the passed in path as     opposed to solely from the sanitized output of the path verification step. This issue affects: Document     Foundation LibreOffice 6.2 versions prior to 6.2.7; 6.3 versions prior to 6.3.1. (CVE-2019-9854)
