Synopsis |
16 |
======== |
17 |
|
18 |
Qt is vulnerable to a buffer overflow which could potentially lead to |
19 |
the execution of arbitrary code. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Qt is a cross-platform GUI toolkit used by KDE. |
25 |
|
26 |
Affected packages |
27 |
================= |
28 |
|

Package / Vulnerable / Unaffected |

32 |
1 x11-libs/qt < 3.3.4-r8 >= 3.3.4-r8 |
33 |
|
34 |
Description |
35 |
=========== |
36 |
|
37 |
Qt links to a bundled vulnerable version of zlib when emerged with the |
38 |
zlib USE-flag disabled. This may lead to a buffer overflow. |
39 |
|
40 |
Impact |
41 |
====== |
42 |
|
43 |
By creating a specially crafted compressed data stream, attackers can |
44 |
overwrite data structures for applications that use Qt, resulting in a |
45 |
Denial of Service or potentially arbitrary code execution. |
46 |
|
47 |
Workaround |
48 |
========== |
49 |
|
50 |
Emerge Qt with the zlib USE-flag enabled. |
51 |
|
52 |
Resolution |
53 |
========== |
54 |
|
55 |
All Qt users should upgrade to the latest version: |
56 |
|
57 |
# emerge --sync |
58 |
# emerge --ask --oneshot --verbose ">=x11-libs/qt-3.3.4-r8" |
