LibreOffice before 2017-01-02 has an out-of-bounds write caused by a heap-based buffer overflow related to the tools::Polygon::Insert function in tools/source/generic/poly.cxx.

The remote Redhat Enterprise Linux 6 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: Multiple out-of-bounds overflows in lwp filter (CVE-2016-0795)

  - libreoffice: heap-based buffer overflow related to the ReadJPEG function (CVE-2017-8358)

  - LibreOffice 3.5.x before 3.5.7.2 and 3.6.x before 3.6.1, and OpenOffice.org (OOo), allows remote attackers     to cause a denial of service (NULL pointer dereference) via a crafted (1) odt file to vcllo.dll, (2) ODG     (Drawing document) file to svxcorelo.dll, (3) PolyPolygon record in a .wmf (Window Meta File) file     embedded in a ppt (PowerPoint) file to tllo.dll, or (4) xls (Excel) file to scfiltlo.dll. (CVE-2012-4233)

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

LibreOffice was updated to version 5.3.5.2, bringing new features and enhancements :

Writer :

  - New 'Go to Page' dialog for quickly jumping to another     page.

  - Support for 'Table Styles'.

  - New drawing tools were added.

  - Improvements in the toolbar.

  - Borderless padding is displayed.

Calc :

  - New drawing tools were added.

  - In new installations the default setting for new     documents is now 'Enable wildcards in formulas' instead     of regular expressions.

  - Improved compatibility with ODF 1.2

Impress :

  - Images inserted via 'Photo Album' can now be linked     instead of embedded in the document.

  - When launching Impress, a Template Selector allows you     to choose a Template to start with.

  - Two new default templates: Vivid and Pencil.

  - All existing templates have been improved.

Draw :

  - New arrow endings, including Crow's foot notation's     ones.

Base :

  - Firebird has been upgraded to version 3.0.0. It is     unable to read back Firebird 2.5 data, so embedded     Firebird odb files created in LibreOffice version up to     5.2 cannot be opened with LibreOffice 5.3.

Some security issues have also been fixed :

  - CVE-2017-7870: An out-of-bounds write caused by a     heap-based buffer overflow related to the     tools::Polygon::Insert function.

  - CVE-2017-7882: An out-of-bounds write related to the     HWPFile::TagsRead function.

An update for libreoffice is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

LibreOffice is an open source, community-developed office productivity suite. It includes key desktop applications, such as a word processor, a spreadsheet, a presentation manager, a formula editor, and a drawing program.

The remote host is affected by the vulnerability described in GLSA-201706-28 (LibreOffice: Multiple vulnerabilities)

    Multiple vulnerabilities have been discovered in LibreOffice. Please       review the CVE identifiers referenced below for details.
  Impact :

    A remote attacker could entice a user to open a specially crafted file       using LibreOffice, possibly resulting in execution of arbitrary code with       the privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known workaround at this time.

- CVE-2017-7870 Heap-buffer-overflow in WMF filter

  - CVE-2016-10327 Heap-buffer-overflow in EMF filter

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3273-1 advisory.

    It was discovered that LibreOffice incorrectly handled EMF image files. If a user were tricked into     opening a specially crafted EMF image file, a remote attacker could cause LibreOffice to crash, and     possibly execute arbitrary code.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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

It was discovered that a buffer overflow in processing Windows Metafiles may result in denial of service or the execution of arbitrary code if a malformed document is opened.

CVE-2017-3157

Ben Hayak discovered that objects embedded in Writer and Calc documents may result in information disclosure. Please see https://www.libreoffice.org/about-us/security/advisories/cve-2017-3157 / for additional information.

CVE-2017-7870

An out-of-bounds write caused by a heap-based buffer overflow was found in the Polygon class.

For Debian 7 'Wheezy', these problems have been fixed in version 1:3.5.4+dfsg2-0+deb7u9.

We recommend that you upgrade your libreoffice packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of LibreOffice installed on the remote Mac OS X or macOS host is prior to 5.1, 5.1.x prior to 5.1.6, or 5.2.x prior to 5.2.5.
It is, therefore, affected by multiple vulnerabilities :

  - An overflow condition exists when processing EMF files,     specifically in the EnhWMFReader::ReadEnhWMF() function     within file vcl/source/filter/wmf/enhwmf.cxx, due to     improper validation of a certain offset value in the     header that precedes bitmap data. An unauthenticated,     remote attacker can exploit this, via a specially     crafted enhanced metafile file (EMF), to cause a denial     of service condition or the execution of arbitrary code.
    Note that this vulnerability does not affect version     5.1.x. (CVE-2016-10327)

  - A file disclosure vulnerability exists due to a flaw in     the content preview feature when handling embedded     objects. An unauthenticated, remote attacker can exploit     this, via a specially crafted file, to disclose details     of a file on the hosting system. (CVE-2017-3157)

  - An overflow condition exists in the Polygon::Insert()     function within file tools/source/generic/poly.cxx     when processing polygons in Windows metafiles (WMF) that     under certain circumstances result in polygons with more     points than can represented in LibreOffice's internal     polygon class. An unauthenticated, remote attacker can     exploit this, via a specially crafted WMF file, to cause     a denial of service condition or the execution of     arbitrary code. Note that this vulnerability does not     affect version 5.1.x. (CVE-2017-7870)

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

The version of LibreOffice installed on the remote Windows host is prior to 5.1, 5.1.x prior to 5.1.6, or 5.2.x prior to 5.2.5. It is, therefore, affected by multiple vulnerabilities :

An unauthenticated,     remote attacker can exploit this, via a specially     crafted enhanced metafile file (EMF), to cause a denial     of service condition or the execution of arbitrary code.
    Note that this vulnerability does not affect version     5.1.x. (CVE-2016-10327)

  - A file disclosure vulnerability exists due to a flaw in     the content preview feature when handling embedded     objects. An unauthenticated, remote attacker can exploit     this, via a specially crafted file, to disclose details     of a file on the hosting system. (CVE-2017-3157)

  - An overflow condition exists in the Polygon::Insert()     function within file tools/source/generic/poly.cxx     when processing polygons in Windows metafiles (WMF) that     under certain circumstances result in polygons with more     points than can represented in LibreOffice's internal     polygon class. An unauthenticated, remote attacker can     exploit this, via a specially crafted WMF file, to cause     a denial of service condition or the execution of     arbitrary code. Note that this vulnerability does not     affect version 5.1.x. (CVE-2017-7870)
