34 |
Description |
35 |
=========== |
36 |
|
37 |
FontForge is vulnerable to an error when processing the |
38 |
"CHARSET_REGISTRY" header in font files, which could cause a |
39 |
stack-based buffer overflow. |
40 |
|
41 |
Impact |
42 |
====== |
43 |
|
44 |
A remote attacker could entice a user to open a specially crafted BDF |
45 |
file using FontForge font editor, possibly resulting in the remote |
46 |
execution of arbitrary code with the privileges of the FontForge |
47 |
process, or a Denial of Service (application crash). |
48 |
|
49 |
Workaround |
50 |
========== |
51 |
|
52 |
There is no known workaround at this time. |
53 |
|
54 |
Resolution |
55 |
========== |
56 |
|
57 |
All FontForge users should upgrade to the latest version: |
58 |
|
59 |
# emerge --sync |
60 |
# emerge --ask --oneshot -v ">=media-gfx/fontforge-20110222-r1" |
61 |
