Description

OpenOffice.org is an office productivity suite that includes desktop
applications, such as a word processor, spreadsheet application,
presentation manager, formula editor, and a drawing program.

An array index error and an integer signedness error were found in the way
OpenOffice.org parsed certain Rich Text Format (RTF) files. An attacker
could use these flaws to create a specially-crafted RTF file that, when
opened, would cause OpenOffice.org to crash or, possibly, execute arbitrary
code with the privileges of the user running OpenOffice.org.
(CVE-2010-3451, CVE-2010-3452)

A heap-based buffer overflow flaw and an array index error were found in
the way OpenOffice.org parsed certain Microsoft Office Word documents. An
attacker could use these flaws to create a specially-crafted Microsoft
Office Word document that, when opened, would cause OpenOffice.org to crash
or, possibly, execute arbitrary code with the privileges of the user
running OpenOffice.org. (CVE-2010-3453, CVE-2010-3454)

A heap-based buffer overflow flaw was found in the way OpenOffice.org
parsed certain Microsoft Office PowerPoint files. An attacker could use
this flaw to create a specially-crafted Microsoft Office PowerPoint file
that, when opened, would cause OpenOffice.org to crash or, possibly,
execute arbitrary code with the privileges of the user running
OpenOffice.org. (CVE-2010-4253)

A heap-based buffer overflow flaw was found in the way OpenOffice.org
parsed certain TARGA (Truevision TGA) files. An attacker could use this
flaw to create a specially-crafted TARGA file. If a document containing
this specially-crafted TARGA file was opened, or if a user tried to insert
the file into an existing document, it would cause OpenOffice.org to crash
or, possibly, execute arbitrary code with the privileges of the user
running OpenOffice.org. (CVE-2010-4643)

A directory traversal flaw was found in the way OpenOffice.org handled the
installation of XSLT filter descriptions packaged in Java Archive (JAR)
files, as well as the installation of OpenOffice.org Extension (.oxt)
files. An attacker could use these flaws to create a specially-crafted XSLT
filter description or extension file that, when opened, would cause the
OpenOffice.org Extension Manager to modify files accessible to the user
installing the JAR or extension file. (CVE-2010-3450)

A flaw was found in the script that launches OpenOffice.org. In some
situations, a "." character could be included in the LD_LIBRARY_PATH
variable, allowing a local attacker to execute arbitrary code with the
privileges of the user running OpenOffice.org, if that user ran
OpenOffice.org from within an attacker-controlled directory.
(CVE-2010-3689)

Red Hat would like to thank OpenOffice.org for reporting the CVE-2010-3451,
CVE-2010-3452, CVE-2010-3453, CVE-2010-3454, and CVE-2010-4643 issues; and
Dmitri Gribenko for reporting the CVE-2010-3689 issue. Upstream
acknowledges Dan Rosenberg of Virtual Security Research as the original
reporter of the CVE-2010-3451, CVE-2010-3452, CVE-2010-3453, and
CVE-2010-3454 issues.

All OpenOffice.org users are advised to upgrade to these updated packages,
which contain backported patches to correct these issues. All running
instances of OpenOffice.org applications must be restarted for this update
to take effect.
