Synopsis |
16 |
======== |
17 |
|
18 |
There are several bugs in Qt's image-handling code which could lead to |
19 |
crashes or arbitrary code execution. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Qt is a cross-platform GUI toolkit used by KDE. |
25 |
|
26 |
Affected packages |
27 |

Description |
35 |
=========== |
36 |
|
37 |
There are several unspecified bugs in the QImage class which may cause |
38 |
crashes or allow execution of arbitrary code as the user running the Qt |
39 |
application. These bugs affect the PNG, XPM, BMP, GIF and JPEG image |
40 |
types. |
41 |
|
42 |
Impact |
43 |
====== |
44 |
|
45 |
An attacker may exploit these bugs by causing a user to open a |
46 |
carefully-constructed image file in any one of these formats. This may |
47 |
be accomplished through e-mail attachments (if the user uses KMail), or |
48 |
by simply placing a malformed image on a website and then convicing the |
49 |
user to load the site in a Qt-based browser (such as Konqueror). |
50 |
|
51 |
Workaround |
52 |
========== |
53 |
|
54 |
There is no known workaround at this time. All users are encouraged to |
55 |
upgrade to the latest available version of Qt. |
56 |
|
57 |
Resolution |
58 |
========== |
59 |
|
60 |
All Qt users should upgrade to the latest version: |
61 |
|
62 |
# emerge sync |
63 |
|
64 |
# emerge -pv ">=x11-libs/qt-3.3.3" |
65 |
# emerge ">=x11-libs/qt-3.3.3" |
66 |
