Synopsis |
| 16 |
======== |
| 17 |
|
| 18 |
GPdf, KPDF and KOffice all include vulnerable xpdf code to handle PDF |
| 19 |
files, making them vulnerable to execution of arbitrary code upon |
| 20 |
viewing a malicious PDF file. |
| 21 |
|
| 22 |
Background |
| 23 |
========== |
| 24 |
|
| 25 |

Description |
| 46 |
=========== |
| 47 |
|
| 48 |
GPdf, KPDF and KOffice all include xpdf code to handle PDF files. xpdf |
| 49 |
is vulnerable to multiple integer overflows, as described in GLSA |
| 50 |
200410-20. |
| 51 |
|
| 52 |
Impact |
| 53 |
====== |
| 54 |
|
| 55 |
An attacker could entice a user to open a specially-crafted PDF file, |
| 56 |
potentially resulting in execution of arbitrary code with the rights of |
| 57 |
the user running the affected utility. |
| 58 |
|
| 59 |
Workaround |
| 60 |
========== |
| 61 |
|
| 62 |
There is no known workaround at this time. |
| 63 |
|
| 64 |
Resolution |
| 65 |
========== |
| 66 |
|
| 67 |
All GPdf users should upgrade to the latest version: |
| 68 |
|
| 69 |
# emerge --sync |
| 70 |
# emerge --ask --oneshot --verbose ">=app-text/gpdf-0.132-r1" |
| 71 |
|
| 72 |
All KDE users should upgrade to the latest version of kdegraphics: |
| 73 |
|
| 74 |
# emerge --sync |
| 75 |
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.3.0-r1" |
| 76 |
|
| 77 |
All KOffice users should upgrade to the latest version: |
| 78 |
|
| 79 |
# emerge --sync |
| 80 |
# emerge --ask --oneshot --verbose ">=app-office/koffice-1.3.3-r1" |
| 81 |
