CVE-2015-1774

Updated libreoffice packages fix security vulnerability:

The HWP filter in LibreOffice before 4.3.7 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 (CVE-2015-1774).

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.

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.

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)
