3. 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.

This update also fixes the following bug:

* OpenOffice.org did not create a lock file when opening a file that was on a share mounted via SFTP. Additionally, if there was a lock file, it was ignored. This could result in data loss if a file in this situation was opened simultaneously by another user. (BZ#671087)

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.
