Multiple vulnerabilities have been found in Asterisk: |
45 |
</p> |
46 |
<ul> |
47 |
<li>Russel Bryant reported a stack buffer overflow in the IAX2 channel |
48 |
driver (chan_iax2) when bridging calls between chan_iax2 and any |
49 |
channel driver that uses RTP for media (CVE-2007-3762).</li> |
50 |
<li>Chris |
51 |
Clark and Zane Lackey (iSEC Partners) reported a NULL pointer |
52 |
dereference in the IAX2 channel driver (chan_iax2) |
53 |
(CVE-2007-3763).</li> |
54 |
<li>Will Drewry (Google Security) reported a |
55 |
vulnerability in the Skinny channel driver (chan_skinny), resulting in |
56 |
an overly large memcpy (CVE-2007-3764).</li> |
57 |
<li>Will Drewry (Google |
58 |
Security) reported a vulnerability in the IAX2 channel driver |
59 |
(chan_iax2), that does not correctly handle unauthenticated |
60 |
transactions using a 3-way handshake (CVE-2007-4103).</li> |
61 |
</ul> |

<impact type="high"> |
64 |
<p> |
65 |
By sending a long voice or video RTP frame, a remote attacker could |
66 |
possibly execute arbitrary code on the target machine. Sending |
67 |
specially crafted LAGRQ or LAGRP frames containing information elements |
68 |
of IAX frames, or a certain data length value in a crafted packet, or |
69 |
performing a flood of calls not completing a 3-way handshake, could |
70 |
result in a Denial of Service. |
71 |
</p> |
72 |
</impact> |
73 |
<workaround> |
74 |
<p> |
75 |
There is no known workaround at this time. |
76 |

<p> |
80 |
All Asterisk users should upgrade to the latest version: |
81 |
</p> |
82 |
<code> |
83 |
# emerge --sync |
84 |
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.17-r1"</code> |
