Multiple vulnerabilities have been discovered in the IAX2 channel |
51 |
driver when performing the 3-way handshake (CVE-2008-1897), when |
52 |
handling a large number of POKE requests (CVE-2008-3263), when handling |
53 |
authentication attempts (CVE-2008-5558) and when handling firmware |
54 |
download (FWDOWNL) requests (CVE-2008-3264). Asterisk does also not |
55 |
correctly handle SIP INVITE messages that lack a "From" header |
56 |
(CVE-2008-2119), and responds differently to a failed login attempt |
57 |
depending on whether the user account exists (CVE-2008-3903, |
58 |
CVE-2009-0041). |

<impact type="normal"> |
62 |
<p> |
63 |
Remote unauthenticated attackers could send specially crafted data to |
64 |
Asterisk, possibly resulting in a Denial of Service via a daemon crash, |
65 |
call-number exhaustion, CPU or traffic consumption. Remote |
66 |
unauthenticated attackers could furthermore enumerate valid usernames |
67 |
to facilitate brute force login attempts. |
68 |
</p> |

70 |
<workaround> |
71 |
<p> |
72 |
There is no known workaround at this time. |
73 |
</p> |
74 |
</workaround> |
75 |
<resolution> |
76 |
<p> |
77 |
All Asterisk users should upgrade to the latest version: |
78 |

<code> |

# emerge --sync |
81 |
# emerge --ask --oneshot --verbose ">=net-misc/asterisk-1.2.32"</code> |
