Security update: Update to LibreOffice 4.4.7
Location: OI-SFE packaging
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.

It was discovered that LibreOffice did not properly restrict automatic link
updates. By tricking a victim into opening specially crafted documents, an
attacker could possibly use this flaw to disclose contents of files
accessible by the victim. (CVE-2015-4551)
An integer underflow flaw leading to a heap-based buffer overflow when
parsing PrinterSetup data was discovered. By tricking a user into opening a
specially crafted document, an attacker could possibly exploit this flaw to
execute arbitrary code with the privileges of the user opening the file.
(CVE-2015-5212)

An integer overflow flaw, leading to a heap-based buffer overflow, was
found in the way LibreOffice processed certain Microsoft Word .doc files.
By tricking a user into opening a specially crafted Microsoft Word .doc
document, an attacker could possibly use this flaw to execute arbitrary
code with the privileges of the user opening the file. (CVE-2015-5213)
It was discovered that LibreOffice did not properly sanity check bookmark
indexes. By tricking a user into opening a specially crafted document, an
attacker could possibly use this flaw to execute arbitrary code with the
privileges of the user opening the file. (CVE-2015-5214)
All libreoffice users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues.
