openoffice.org vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 10.04 LTS

Summary:

OpenOffice.org could be made to crash or potentially run programs as your
login if it opened a specially crafted file.

Software Description:
- openoffice.org: Office productivity suite

Details:

A stack-based buffer overflow was discovered in the Lotus Word Pro import
filter in OpenOffice.org. The default compiler options for affected
releases should reduce the vulnerability to a denial of service.

Huzaifa Sidhpurwala discovered that OpenOffice.org could be made to crash
if it opened a specially crafted Word document. (CVE-2011-2713)

Integer overflows were discovered in the graphics loading code of several
different image types. If a user were tricked into opening a specially
crafted file, an attacker could cause OpenOffice.org to crash or possibly
execute arbitrary code with the privileges of the user invoking the
program. (CVE-2012-1149)

Sven Jacobi discovered an integer overflow when processing Escher graphics
records. If a user were tricked into opening a specially crafted PowerPoint
file, an attacker could cause OpenOffice.org to crash or possibly execute
arbitrary code with the privileges of the user invoking the program.
(CVE-2012-2334)

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 10.04 LTS:
