Synopsis |
16 |
======== |
17 |
|
18 |
A security vulnerability in the iaxclient library could lead to the |
19 |
execution of arbitrary code by a remote attacker. |
20 |
|
21 |
Background |
22 |
========== |
23 |
|
24 |
Kiax is a graphical softphone supporting the IAX protocol (Inter |
25 |
Asterisk eXchange), which allows PC users to make VoIP calls to |
26 |
Asterisk servers. |
27 |
|
28 |
Affected packages |
29 |
================= |
30 |
|
31 |
------------------------------------------------------------------- |
32 |
Package / Vulnerable / Unaffected |
33 |
------------------------------------------------------------------- |
34 |
1 net-misc/kiax < 0.8.5_p1 >= 0.8.5_p1 |
35 |
|
36 |
Description |
37 |
=========== |
38 |
|
39 |
The iax_net_read function in the iaxclient library fails to properly |
40 |
handle IAX2 packets with truncated full frames or mini-frames. These |
41 |
frames are detected in a length check but processed anyway, leading to |
42 |
buffer overflows. |
43 |
|
44 |
Impact |
45 |
====== |
46 |
|
47 |
By sending a specially crafted IAX2 packet, an attacker could execute |
48 |
arbitrary code with the permissions of the user running Kiax. |
49 |
|
50 |
Workaround |
51 |
========== |
52 |
|
53 |
There is no known workaround at this time. |
54 |
|
55 |
Resolution |
56 |
========== |
57 |
|
58 |
All Kiax users should upgrade to the latest version: |
59 |
|
60 |
# emerge --sync |
61 |
# emerge --ask --oneshot --verbose ">=net-misc/kiax-0.8.5_p1" |
