Description |
| 39 |
=========== |
| 40 |
|
| 41 |
KPdf includes Xpdf code to handle PDF files. Dirk Mueller discovered |
| 42 |
that the Xpdf code is vulnerable a heap based overflow in the splash |
| 43 |
rasterizer engine. |
| 44 |
|
| 45 |
Impact |
| 46 |
====== |
| 47 |
|
| 48 |
An attacker could entice a user to open a specially crafted PDF file |
| 49 |
with Kpdf, potentially resulting in the execution of arbitrary code |
| 50 |
with the rights of the user running the affected application. |
| 51 |
|
| 52 |
Workaround |
| 53 |
========== |
| 54 |
|
| 55 |
There is no known workaround at this time. |
| 56 |
|
| 57 |
Resolution |
| 58 |
========== |
| 59 |
|
| 60 |
All kdegraphics users should upgrade to the latest version: |
| 61 |
|
| 62 |
# emerge --sync |
| 63 |
# emerge --ask --oneshot --verbose ">=kde-base/kdegraphics-3.4.3-r4" |
| 64 |
|
| 65 |
All Kpdf users should upgrade to the latest version: |
