15 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"
