CVE-2015-8947

hb-ot-layout-gpos-table.hh in HarfBuzz before 1.0.5 allows remote attackers to cause a denial of service (buffer over-read) or possibly have unspecified other impact via crafted data, a different vulnerability than CVE-2016-2052.

Two memory access issues, including a heap-based buffer overflow (CVE-2015-8947) and incorrect table length check (CVE-2016-2052) could lead to a denial of service when rendering a crafted OpenType font.

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.
