Synopsis |
16 |
======== |
17 |
|
18 |
Multiple vulnerabilities have been discovered in QtCore and QtGui, |
19 |
possibly resulting in execution of arbitrary code, Denial of Service, |
20 |
or man-in-the-middle attacks. |
21 |
|
22 |
Background |
23 |
========== |
24 |
|

Description |
40 |
=========== |
41 |
|
42 |
Multiple vulnerabilities have been discovered in QtCore and QtGui. |
43 |
Please review the CVE identifiers referenced below for details. |
44 |
|
45 |
Impact |
46 |
====== |
47 |
|
48 |
A remote attacker could entice a user to open a specially crafted file |
49 |
with an application linked against QtCore or QtGui, possibly resulting |
50 |
in execution of arbitrary code with the privileges of the process or a |
51 |
Denial of Service condition. Furthermore, a remote attacker might |
52 |
employ a specially crafted certificate to conduct man-in-the-middle |
53 |
attacks on SSL connections. |
54 |
|
55 |
Workaround |
56 |
========== |
57 |
|
58 |
There is no known workaround at this time. |
59 |
|
60 |
Resolution |
61 |
========== |
62 |
|
63 |
All QtCore users should upgrade to the latest version: |
64 |
|
65 |
# emerge --sync |
66 |
# emerge --ask --oneshot --verbose ">=dev-qt/qtcore-4.8.4-r2" |
67 |
|
68 |
All QtGui users should upgrade to the latest version: |
69 |
|
70 |
# emerge --sync |
71 |
# emerge --ask --oneshot --verbose ">=dev-qt/qtgui-4.8.4-r1" |
72 |
|
73 |
Packages which depend on this library may need to be recompiled. Tools |
74 |
such as revdep-rebuild may assist in identifying some of these |
75 |
packages. |
