Description |
47 |
=========== |
48 |
|
49 |
KPDF includes code from xpdf that is vulnerable to an integer overflow |
50 |
in the StreamPredictor::StreamPredictor() function. |
51 |
|
52 |
Impact |
53 |
====== |
54 |
|
55 |
A remote attacker could entice a user to open a specially crafted PDF |
56 |
file in KWord or KPDF that would exploit the integer overflow to cause |
57 |
a stack-based buffer overflow in the StreamPredictor::getNextLine() |
58 |
function, possibly resulting in the execution of arbitrary code with |
59 |
the privileges of the user running the application. |
60 |
|
61 |
Workaround |
62 |
========== |
63 |
|
64 |
There is no known workaround at this time. |
65 |
|
