CVE-2017-7870

LibreOffice before 2017-01-02 has an out-of-bounds write caused by a heap-based buffer overflow related to the tools::Polygon::Insert function in tools/source/generic/poly.cxx.

These are all security issues fixed in the libreoffice-7.1.5.2-3.13 package on the GA media of openSUSE Tumbleweed.

LibreOffice was updated to version 5.3.3.2, bringing new features and enhancements:

Writer:

• New 'Go to Page' dialog for quickly jumping to another page.
• Support for 'Table Styles'.
• New drawing tools were added.
• Improvements in the toolbar.
• Borderless padding is displayed.

Calc:

• New drawing tools were added.
• In new installations the default setting for new documents is now 'Enable wildcards in formulas' instead of regular expressions.
• Improved compatibility with ODF 1.2

Impress:

• Images inserted via 'Photo Album' can now be linked instead of embedded in the document.
• When launching Impress, a Template Selector allows you to choose a Template to start with.
• Two new default templates: Vivid and Pencil.
• All existing templates have been improved.

Draw:

• New arrow endings, including Crow's foot notation's ones.

Base:

• Firebird has been upgraded to version 3.0.0. It is unable to read back Firebird 2.5 data, so embedded Firebird odb files created in LibreOffice version up to 5.2 cannot be opened with LibreOffice 5.3.

Some security issues have also been fixed:

• CVE-2017-7870: An out-of-bounds write caused by a heap-based buffer overflow related to the tools::Polygon::Insert function.
• CVE-2017-7882: An out-of-bounds write related to the HWPFile::TagsRead function.
• CVE-2017-8358: an out-of-bounds write caused by a heap-based buffer overflow related to the ReadJPEG function.
• CVE-2016-10327: An out-of-bounds write caused by a heap-based buffer overflow related to the EnhWMFReader::ReadEnhWMF function.
• CVE-2017-9433: An out-of-bounds write caused by a heap-based buffer overflow related to the MsWrd1Parser::readFootnoteCorrespondance function in libmwaw.

It was discovered that LibreOffice incorrectly handled EMF image files. If a user were tricked into opening a specially crafted EMF image file, a remote attacker could cause LibreOffice to crash, and possibly execute arbitrary code.
