Synopsis |
19 |
======== |
20 |
|
21 |
Vulnerabilities in KDE URI handlers makes your system vulnerable to |
22 |
various attacks. |
23 |
|
24 |
Background |
25 |
========== |
26 |
|
27 |
The K Desktop Environment (KDE) is a powerful Free Software graphical |
28 |
desktop environment. KDE makes use of URI handlers to trigger various |
29 |
programs when specific URLs are received. |
30 |
|
31 |
Affected packages |
32 |
================= |
33 |
|

------------------------------------------------------------------- |
35 |
Package / Vulnerable / Unaffected |
36 |
------------------------------------------------------------------- |
37 |
1 kde-base/kdelibs <= 3.2.2 >= 3.2.2-r1 |
38 |
= 3.1.5-r1 |
39 |
|
40 |
Description |
41 |
=========== |
42 |
|
43 |
The telnet, rlogin, ssh and mailto URI handlers in KDE do not check for |
44 |
'-' at the beginning of the hostname passed. By crafting a malicious |
45 |
URI and entice an user to click on it, it is possible to pass an option |
46 |
to the programs started by the handlers (typically telnet, kmail...). |
47 |
|
48 |
Impact |
49 |
====== |
50 |
|
51 |
If the attacker controls the options passed to the URI handling |
52 |
programs, it becomes possible for example to overwrite arbitrary files |
53 |
(possibly leading to denial of service), to open kmail on an |
54 |
attacker-controlled remote display or with an alternate configuration |
55 |
file (possibly leading to control of the user account). |
56 |
|
57 |
Workaround |
58 |
========== |
59 |
|
60 |
There is no known workaround at this time. All users are advised to |
61 |
upgrade to a corrected version of kdelibs. |
62 |
|
63 |
Resolution |
64 |
========== |
65 |
|
66 |
Users of KDE 3.1 should upgrade to the corrected version of kdelibs: |
67 |
|
68 |
# emerge sync |
69 |
|
70 |
# emerge -pv "=kde-base/kdelibs-3.1.5-r1" |
71 |
# emerge "=kde-base/kdelibs-3.1.5-r1" |
72 |
|
73 |
Users of KDE 3.2 should upgrade to the latest available version of |
74 |
kdelibs: |
75 |
|
76 |
# emerge sync |
77 |
|
78 |
# emerge -pv ">=kde-base/kdelibs-3.2.2-r1" |
79 |
# emerge ">=kde-base/kdelibs-3.2.2-r1" |
