Alexander Cherepanov discovered that LibreOffice incorrectly handled certain RTF files. If a user were tricked into opening a specially crafted RTF document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2014-9093)

It was discovered that LibreOffice incorrectly handled certain HWP files. If a user were tricked into opening a specially crafted HWP document, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code. (CVE-2015-1774).

US-CERT/NIST reports :

The HWP filter in LibreOffice before 4.3.7 and 4.4.x before 4.4.2 and Apache OpenOffice before 4.1.2 allows remote attackers to cause a denial of service (crash) or possibly execute arbitrary code via a crafted HWP document, which triggers an out-of-bounds write.

This update brings LibreOffice to version 5.0.2, a major version update.

It brings lots of new features, bugfixes and also security fixes.

Features as seen on http://www.libreoffice.org/discover/new-features/

  - LibreOffice 5.0 ships an impressive number of new     features for its spreadsheet module, Calc: complex     formulae image cropping, new functions, more powerful     conditional formatting, table addressing and much more.
    Calc's blend of performance and features makes it an     enterprise-ready, heavy duty spreadsheet application     capable of handling all kinds of workload for an     impressive range of use cases

  - New icons, major improvements to menus and sidebar : no     other LibreOffice version has looked that good and     helped you be creative and get things done the right     way. In addition, style management is now more intuitive     thanks to the visualization of styles right in the     interface.

  - LibreOffice 5 ships with numerous improvements to     document import and export filters for MS Office, PDF,     RTF, and more. You can now timestamp PDF documents     generated with LibreOffice and enjoy enhanced document     conversion fidelity all around.

The Pentaho Flow Reporting Engine is now added and used.

Security issues fixed :

  - CVE-2014-8146: The resolveImplicitLevels function in     common/ubidi.c in the Unicode Bidirectional Algorithm     implementation in ICU4C in International Components for     Unicode (ICU) before 55.1 did not properly track     directionally isolated pieces of text, which allowed     remote attackers to cause a denial of service     (heap-based buffer overflow) or possibly execute     arbitrary code via crafted text.

  - CVE-2014-8147: The resolveImplicitLevels function in     common/ubidi.c in the Unicode Bidirectional Algorithm     implementation in ICU4C in International Components for     Unicode (ICU) before 55.1 used an integer data type that     is inconsistent with a header file, which allowed remote     attackers to cause a denial of service (incorrect malloc     followed by invalid free) or possibly execute arbitrary     code via crafted text.

  - CVE-2015-4551: An arbitrary file disclosure     vulnerability in Libreoffice and Openoffice Calc and     Writer was fixed.

  - CVE-2015-1774: The HWP filter in LibreOffice allowed     remote attackers to cause a denial of service (crash) or     possibly execute arbitrary code via a crafted HWP     document, which triggered an out-of-bounds write.

  - CVE-2015-5212: A LibreOffice 'PrinterSetup Length'     integer underflow vulnerability could be used by     attackers supplying documents to execute code as the     user opening the document.

  - CVE-2015-5213: A LibreOffice 'Piece Table Counter'     invalid check design error vulnerability allowed     attackers supplying documents to execute code as the     user opening the document.

  - CVE-2015-5214: Multiple Vendor LibreOffice Bookmark     Status Memory Corruption Vulnerability allowed attackers     supplying documents to execute code as the user opening     the document.

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

It was discovered that missing input sanitising in Libreoffice's filter for HWP documents may result in the execution of arbitrary code if a malformed document is opened.

The version of Apache OpenOffice installed on the remote host is a version prior to 4.1.2. It is, therefore, affected by the following vulnerabilities :

  - An overflow condition exists in the Hangul Word     Processor (HWP) filter due to improper validation of     user-supplied input. A remote attacker can exploit this,     via a specially crafted HWP document, to cause a denial     of service condition or the execution of arbitrary code.
    (CVE-2015-1774)

  - An information disclosure vulnerability exists due to     the use of stored LinkUpdateMode configuration     information in OpenDocument Format files and templates     when handling links. A remote attacker can exploit this,     via a specially crafted ODF document, to to obtain     sensitive information. (CVE-2015-4551)

  - An integer underflow condition exists in the     ReadJobSetup() function due to improper validation of     user-supplied input when handling printer settings. A     remote attacker can exploit this, via specially crafted     PrinterSetup data in an ODF document, to cause a denial     of service condition or the execution of arbitrary code.
    (CVE-2015-5212)

  - An integer underflow condition exists in the     WW8ScannerBase::OpenPieceTable() function due to     improper validation of user-supplied input when handling     the PieceTable counter. A remote attacker can exploit     this, via a specially crafted .DOC file, to cause a     denial of service condition or the execution of     arbitrary code. (CVE-2015-5213)

  - A memory corruption issue exists in     'filter/ww8/ww8scan.cxx' due to improper validation of     user-supplied input when handling bookmark status     positions. A remote attacker can exploit this, via a     specially crafted document, to cause a denial of service     condition or the execution of arbitrary code.
    (CVE-2015-5214)

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.

Fix some .docx import crashes. And finally fix the re-render of checked->unchecked checkbox transition
