An anonymous contributor working with VeriSign iDefense Labs discovered that libreoffice, a full-featured office productivity suite, did not correctly handle Lotus WordPro files. This would enable an attacker to crash the program, or execute arbitrary code, by supplying a specially crafted LWP file.

- CVE-2016-0794 and CVE-2016-0795 LotusWordPro filter     security fixes

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of LibreOffice installed on the remote Windows host is prior to 5.0.5. It is, therefore, affected by multiple vulnerabilities :

  - A remote code execution vulnerability exists due to     improper validation of user-supplied input when handling     LotusWordPro (LWP) documents. A remote attacker can     exploit this, via a crafted LWP document, to corrupt     memory, resulting in a denial of service condition or     the execution of arbitrary code. (CVE-2016-0794)

  - A remote code execution vulnerability exists due to     improper validation of user-supplied input when handling     LwpTocSuperLayout records. A remote attacker can exploit     this, via a crafted LwpTocSuperLayout record in a     LotusWordPro (LWP) document, to corrupt memory,     resulting in a denial of service condition or the     execution of arbitrary code. (CVE-2016-0795)

Note that Nessus has not attempted to exploit these issues but has instead relied only on the application's self-reported version number.

This libreoffice update to version 5.0.6.3 fixes the following issues :

Security issues fixed :

LibreOffice was updated to version 5.1.3.2, bringing many new features and bug fixes.

Two security issues have been fixed :

  - CVE-2016-0795: LibreOffice allowed remote attackers to     cause a denial of service (memory corruption) or     possibly have unspecified other impact via a crafted     LwpTocSuperLayout record in a LotusWordPro (lwp)     document.

  - CVE-2016-0794: The lwp filter in LibreOffice allowed     remote attackers to cause a denial of service (memory     corruption) or possibly have unspecified other impact     via a crafted LotusWordPro (lwp) document.

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.

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.

The following packages have been upgraded to a newer upstream version:
libreoffice (5.0.6.2). (BZ#1290148)

Security Fix(es) :

* Multiple flaws were found in the Lotus Word Pro (LWP) document format parser in LibreOffice. By tricking a user into opening a specially crafted LWP document, an attacker could possibly use this flaw to execute arbitrary code with the privileges of the user opening the file. (CVE-2016-0794, CVE-2016-0795)
