Description |
37 |
=========== |
38 |
|
39 |
Toth Andras has discovered a typographic mistake in the "fbgs" script, |
40 |
shipped with fbida if the "fbcon" and "pdf" USE flags are both enabled. |
41 |
This script runs "gs" without the -dSAFER option, thus allowing a |
42 |
PostScript file to execute, delete or create any kind of file on the |
43 |
system. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker can entice a vulnerable user to view a malicious |
49 |
PostScript or PDF file with fbgs, which may result with the execution |
50 |
of arbitrary code. |
51 |
|
52 |
Workaround |
53 |
========== |
54 |
|
55 |
There is no known workaround at this time. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All fbida users with the "fbcon" and "pdf" USE flags both enabled |
61 |
should upgrade to the latest version: |
62 |
|
63 |
# emerge --sync |
64 |
# emerge --ask --oneshot --verbose ">=media-gfx/fbida-2.03-r4" |
65 |
