(RHSA-2015:1458) Moderate: libreoffice security, bug fix, and enhancement update

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.

A flaw was found in the way the LibreOffice HWP (Hangul Word Processor)
file filter processed certain HWP documents. An attacker able to trick a
user into opening a specially crafted HWP document could possibly use this
flaw to execute arbitrary code with the privileges of the user opening that
document. (CVE-2015-1774)

The libreoffice packages have been upgraded to upstream version 4.2.8.2,
which provides a number of bug fixes and enhancements over the previous
version, including:

• OpenXML interoperability has been improved.

• This update adds additional statistics functions to the Calc application,
  thus improving interoperability with Microsoft Excel and its “Analysis
  ToolPak” add-in.

• Various performance improvements have been implemented in Calc.

• This update adds new import filters for importing files from the Appple
  Keynote and Abiword applications.

• The export filter for the MathML markup language has been improved.

• This update adds a new start screen that includes thumbnails of recently
  opened documents.

• A visual clue is now displayed in the Slide Sorter window for slides with
  transitions or animations.

• This update improves trend lines in charts.

• LibreOffice now supports BCP 47 language tags.

For a complete list of bug fixes and enhancements provided by this rebase,
see the libreoffice change log linked from the References section.
