Description |
40 |
=========== |
41 |
|
42 |
Dirk Mueller has reported a vulnerability in Xpdf. It is caused by a |
43 |
missing boundary check in the splash rasterizer engine when handling |
44 |
PDF splash images with overly large dimensions. |
45 |
|
46 |
Impact |
47 |
====== |
48 |
|
49 |
By sending a specially crafted PDF file to a victim, an attacker could |
50 |
cause an overflow, potentially resulting in the execution of arbitrary |
51 |
code with the privileges of the user running the application. |
52 |
|
53 |
Workaround |
54 |
========== |
55 |
|
56 |
There is no known workaround at this time. |
57 |
|
58 |
Resolution |
59 |
========== |
60 |
