Synopsis |
16 |
======== |
17 |
|
18 |
A heap-based buffer overflow in SWFTools could result in the execution |
19 |
of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
SWFTools is a collection of SWF manipulation and generation utilities |
25 |
written by Rainer Böhme and Matthias Kramm. |
26 |
|
27 |
Affected packages |
28 |
================= |
29 |
|
30 |
------------------------------------------------------------------- |
31 |
Package / Vulnerable / Unaffected |
32 |
------------------------------------------------------------------- |
33 |
1 media-gfx/swftools <= 0.9.1 Vulnerable! |
34 |
------------------------------------------------------------------- |
35 |
NOTE: Certain packages are still vulnerable. Users should migrate |
36 |
to another package if one is available or wait for the |
37 |
existing packages to be marked stable by their |
38 |
architecture maintainers. |
39 |
|
40 |
Description |
41 |
=========== |
42 |
|
43 |
Integer overflow errors in the "getPNG()" function in png.c and the |
44 |
"jpeg_load()" function in jpeg.c could cause a heap-based buffer |
45 |
overflow. |
46 |
|
47 |
Impact |
48 |
====== |
49 |
|
50 |
A remote attacker could entice a user to open a specially crafted PNG |
51 |
or JPEG file, possibly resulting in execution of arbitrary code with |
52 |
the privileges of the process, or a Denial of Service condition. |
53 |
|
54 |
Workaround |
55 |
========== |
56 |
|
57 |
There is no known workaround at this time. |
58 |
|
59 |
Resolution |
60 |
========== |
61 |
|
62 |

63 |
