Use-after-free vulnerability in the socket manager of Impress Remote in LibreOffice 4.x before 4.2.7 and 4.3.x before 4.3.3 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted request to TCP port 1599.

The remote host is affected by the vulnerability described in GLSA-201603-05 (LibreOffice, OpenOffice: Multiple vulnerabilities)

    Multiple vulnerabilities were found in both LibreOffice and OpenOffice       that allow the remote execution of arbitrary code and potential Denial of       Service.  These vulnerabilities may be exploited through multiple vectors       including crafted documents, link handling, printer setup in ODF document       types, DOC file formats, and Calc spreadsheets.  Please review the       referenced CVE&rsquo;s for specific information regarding each.
  Impact :

    A remote attacker could entice a user to open a specially crafted file       using the LibreOffice or OpenOffice suite of software.  Execution of       these attacks could possibly result in the execution of arbitrary code       with the privileges of the process or a Denial of Service condition.
  Workaround :

    There is no known work around at this time.

This update for LibreOffice and some library dependencies (cmis-client, libetonyek, libmwaw, libodfgen, libpagemaker, libreoffice-share-linker, mdds, libwps) fixes the following issues :

It was found that LibreOffice documents executed macros unconditionally, without user approval, when these documents were opened using LibreOffice. An attacker could use this flaw to execute arbitrary code as the user running LibreOffice by embedding malicious VBA scripts in the document as macros. (CVE-2014-0247)

A flaw was found in the OLE (Object Linking and Embedding) generation in LibreOffice. An attacker could use this flaw to embed malicious OLE code in a LibreOffice document, allowing for arbitrary code execution.
(CVE-2014-3575)

A use-after-free flaw was found in the 'Remote Control' capabilities of the LibreOffice Impress application. An attacker could use this flaw to remotely execute code with the permissions of the user running LibreOffice Impress. (CVE-2014-3693)

The libreoffice packages have been upgraded to upstream version 4.2.6.3, which provides a number of bug fixes and enhancements over the previous version. Among others :

  - Improved OpenXML interoperability.

  - Additional statistic functions in Calc (for     interoperability with Excel and Excel's Add-in 'Analysis     ToolPak').

  - Various performance improvements in Calc.

  - Apple Keynote and Abiword import.

  - Improved MathML export.

  - New Start screen with thumbnails of recently opened     documents.

  - Visual clue in Slide Sorter when a slide has a     transition or an animation.

  - Improvements for trend lines in charts.

  - Support for BCP-47 language tags.

A version of LibreOffice is installed on the remote Windows host that is 4.3.x prior to 4.3.3. It is, therefore, affected by a use-after-free vulnerability related to the Impress Remote socket manager that allows denial of service attacks or arbitrary code execution by means of a specially crafted TCP request that causes already freed memory to be dereferenced.

Note that Nessus has not attempted to exploit this issue but has instead relied only on the application's self-reported version number.

libreoffice was updated to version 4.3.3 to fix two security issues :

These security issues were fixed :

  - 'Document as E-mail' vulnerability (bnc#900218).

libreoffice was updated to fix two security issues. &#9; These security issues were fixed :

  - 'Document as E-mail' vulnerability (bnc#900218).

  - Impress Remote Control Use-after-Free Vulnerability     (CVE-2014-3693).

It was discovered that LibreOffice incorrectly handled the Impress remote control port. An attacker could possibly use this issue to cause Impress to crash, resulting in a denial of service, or possibly execute arbitrary code.
