By exploiting the way Apache OpenOffice before 4.1.4 renders embedded objects, an attacker could craft a document that allows reading in a file from the user's filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to send the document back to the attacker. The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back.

The version of Apache OpenOffice installed on the remote host is a version prior to 4.1.4. It is, therefore, affected by multiple Out-of-Bounds vulnerabilities and a file disclosure vulnerability in Calc/Writer.

The Apache Openofffice project reports : CVE-2017-3157: Arbitrary file disclosure in Calc and Writer By exploiting the way OpenOffice renders embedded objects, an attacker could craft a document that allows reading in a file from the user's filesystem. Information could be retrieved by the attacker by, e.g., using hidden sections to store the information, tricking the user into saving the document and convincing the user to sent the document back to the attacker.

The vulnerability is mitigated by the need for the attacker to know the precise file path in the target system, and the need to trick the user into saving the document and sending it back. CVE-2017-9806:
Out-of-Bounds Write in Writer's WW8Fonts Constructor A vulnerability in the OpenOffice Writer DOC file parser, and specifically in the WW8Fonts Constructor, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution. CVE-2017-12607:
Out-of-Bounds Write in Impress' PPT Filter A vulnerability in OpenOffice's PPT file parser, and specifically in PPTStyleSheet, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution. CVE-2017-12608: Out-of-Bounds Write in Writer's ImportOldFormatStyles A vulnerability in OpenOffice Writer DOC file parser, and specifically in ImportOldFormatStyles, allows attackers to craft malicious documents that cause denial of service (memory corruption and application crash) potentially resulting in arbitrary code execution.

An update for libreoffice is now available for Red Hat Enterprise Linux 6.

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. LibreOffice replaces OpenOffice and provides a similar but enhanced and extended office suite.

Security Fix(es) :

* It was found that LibreOffice disclosed contents of a file specified in an embedded object's preview. An attacker could potentially use this flaw to expose details of a system running LibreOffice as an online service via a crafted document. (CVE-2017-3157)

Note that Tenable Network Security has attempted to extract the preceding description block directly from the corresponding Red Hat security advisory. Virtuozzo provides no description for VZLSA advisories. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Bug Fix(es) :

* Previously, an improper resource management caused the LibreOffice Calc spreadsheet application to terminate unexpectedly after closing a dialog window with accessibility support enabled. The resource management has been improved, and the described problem no longer occurs. (BZ#1425536)

* Previously, when an incorrect password was entered for a password protected document, the document has been considered as valid and a fallback attempt to open it as plain text has been made. As a consequence, it could appear that the document succesfully loaded, while just the encrypted unreadable content was shown. A fix has been made to terminate import attempts after entering incorrect password, and now nothing is loaded when a wrong password is entered.
(BZ#1426348)

* Previously, an improper resource management caused the LibreOffice Calc spreadsheet application to terminate unexpectedly during exit, after the Text Import dialog for CSV (Comma-separated Value) files closed, when accessibility support was enabled. The resource management has been improved, and the described problem no longer occurs. (BZ#1425535)

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.

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.
