Synopsis |
16 |
======== |
17 |
|
18 |
The AMD64 x86 emulation Qt library makes use of an insecure version of |
19 |
the Qt library, potentially allowing for the remote execution of |
20 |
arbitrary code. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|
25 |
The AMD64 x86 emulation Qt library for AMD64 emulates the x86 (32-bit) |
26 |
Qt library on the AMD64 (64-bit) architecture. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
1 emul-linux-x86-qtlibs < 10.0 >= 10.0 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
An integer overflow flaw has been found in the pixmap handling of Qt, |
40 |
making the AMD64 x86 emulation Qt library vulnerable as well. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
By enticing a user to open a specially crafted pixmap image in an |
46 |
application using the AMD64 x86 emulation Qt library, a remote attacker |
47 |
could cause an application crash or the remote execution of arbitrary |
48 |
code with the rights of the user running the application. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All AMD64 x86 emulation Qt library users should upgrade to the latest |
59 |
version: |
60 |
|
61 |
# emerge --sync |
62 |
# emerge --ask --oneshot --verbose ">=app-emulation/emul-linux-x86-qtlibs-10.0" |
