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 integer truncation error, leading to a heap-based buffer overflow, was
found in the way the OpenOffice.org Impress presentation application
sanitized a file's dictionary property items. An attacker could use this
flaw to create a specially-crafted Microsoft Office PowerPoint file that,
when opened, would cause OpenOffice.org Impress to crash or, possibly,
execute arbitrary code with the privileges of the user running
OpenOffice.org Impress. (CVE-2010-2935)

the privileges of the user running OpenOffice.org Impress. (CVE-2010-2936)
