Synopsis
Moderate: libreoffice security and bug fix update
Type/Severity
Security Advisory: Moderate
Topic
An update for libreoffice is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Description
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.
Security Fix(es):
- It was found that LibreOffice disclosed contents of a file specified in an embedded object's preview. An attacker could potentially use this flaw to expose details of a system running LibreOffice as an online service via a crafted document. (CVE-2017-3157)
Bug Fix(es):
- Previously, an improper resource management caused the LibreOffice Calc spreadsheet application to terminate unexpectedly after closing a dialog window with accessibility support enabled. The resource management has been improved, and the described problem no longer occurs. (BZ#1425536)
- Previously, when an incorrect password was entered for a password protected document, the document has been considered as valid and a fallback attempt to open it as plain text has been made. As a consequence, it could appear that the document succesfully loaded, while just the encrypted unreadable content was shown. A fix has been made to terminate import attempts after entering incorrect password, and now nothing is loaded when a wrong password is entered. (BZ#1426348)
- Previously, an improper resource management caused the LibreOffice Calc spreadsheet application to terminate unexpectedly during exit, after the Text Import dialog for CSV (Comma-separated Value) files closed, when accessibility support was enabled. The resource management has been improved, and the described problem no longer occurs. (BZ#1425535)
