Description |
| 41 |
=========== |
| 42 |
|
| 43 |
John Heasman of NGSSoftware has discovered integer overflows in the |
| 44 |
EMR_POLYPOLYGON and EMR_POLYPOLYGON16 processing and an error within |
| 45 |
the handling of META_ESCAPE records. |
| 46 |
|
| 47 |
Impact |
| 48 |

| 49 |
|
| 50 |
An attacker could exploit these vulnerabilities to cause heap overflows |
| 51 |
and potentially execute arbitrary code with the privileges of the user |
| 52 |
running OpenOffice.org by enticing the user to open a document |
| 53 |
containing a malicious WMF/EMF file. |
| 54 |
|
| 55 |
Workaround |
| 56 |
========== |
| 57 |
|
| 58 |
There is no known workaround known at this time. |
| 59 |
|
| 60 |
Resolution |
| 61 |
========== |
| 62 |
|
| 63 |
All OpenOffice.org binary users should update to version 2.1.0 or |
| 64 |
later: |
| 65 |
|
| 66 |
# emerge --sync |
| 67 |
# emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.1.0" |
| 68 |
|
| 69 |
All OpenOffice.org users should update to version 2.0.4 or later: |
