Description |
| 41 |
=========== |
| 42 |
|
| 43 |
iDefense Labs reported multiple vulnerabilities in OpenOffice.org: |
| 44 |
|
| 45 |
* multiple heap-based buffer overflows when parsing the "Attribute" |
| 46 |
and "Font" Description records of Quattro Pro (QPRO) files |
| 47 |
(CVE-2007-5745), |
| 48 |
|
| 49 |
* an integer overflow when parsing the EMR_STRETCHBLT record of an |
| 50 |
EMF file, resulting in a heap-based buffer overflow (CVE-2007-5746), |
| 51 |
|
| 52 |
* an integer underflow when parsing Quattro Pro (QPRO) files, |
| 53 |
resulting in an excessive loop and a stack-based buffer overflow |
| 54 |
(CVE-2007-5747), |
| 55 |
|
| 56 |
* and a heap-based buffer overflow when parsing the |
| 57 |
"DocumentSummaryInformation" stream in an OLE file (CVE-2008-0320). |
| 58 |
|
| 59 |
Furthermore, Will Drewry (Google Security) reported vulnerabilities in |
| 60 |
the memory management of the International Components for Unicode |
| 61 |
(CVE-2007-4770, CVE-2007-4771), which was resolved with GLSA 200803-20. |
| 62 |
However, the binary version of OpenOffice.org uses an internal copy of |
| 63 |
said library. |
| 64 |
|
| 65 |
Impact |
| 66 |
====== |
| 67 |
|
| 68 |
A remote attacker could entice a user to open a specially crafted |
| 69 |
document, possibly resulting in the remote execution of arbitrary code |
| 70 |
with the privileges of the user running OpenOffice.org. |
| 71 |
|
| 72 |
Workaround |
| 73 |
========== |
| 74 |
|
| 75 |
There is no known workaround at this time. |
| 76 |
|
| 77 |
Resolution |
| 78 |
========== |
| 79 |
|
| 80 |
All OpenOffice.org users should upgrade to the latest version: |
| 81 |
|
| 82 |
# emerge --sync |
| 83 |
# emerge --ask --oneshot --verbose ">=app-office/openoffice-2.4.0" |
| 84 |
|
| 85 |
All OpenOffice.org binary users should upgrade to the latest version: |
| 86 |
|
| 87 |
# emerge --sync |
| 88 |
# emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.4.0" |
| 89 |
