Summary

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.
