Fetchmail is a remote mail retrieval and forwarding utility. |

46 |
Multiple vulnerabilities have been reported in Fetchmail: |
47 |
</p> |
48 |
<ul> |
49 |
<li>The sdump() function might trigger a heap-based buffer overflow |
50 |
during the escaping of non-printable characters with the high bit set |
51 |
from an X.509 certificate (CVE-2010-0562).</li> |
52 |
<li>The vendor reported |
53 |
that Fetchmail does not properly handle Common Name (CN) fields in |
54 |
X.509 certificates that contain an ASCII NUL character. Specifically, |
55 |
the processing of such fields is stopped at the first occurrence of a |
56 |
NUL character. This type of vulnerability was recently discovered by |
57 |
Dan Kaminsky and Moxie Marlinspike (CVE-2009-2666).</li> |
58 |
</ul> |

<impact type="normal"> |
61 |
<p> |
62 |
A remote attacker could entice a user to connect with Fetchmail to a |
63 |
specially crafted SSL-enabled server in verbose mode, possibly |
64 |
resulting in the execution of arbitrary code with the privileges of the |
65 |
user running the application. NOTE: The issue is only existent on |
66 |
platforms on which char is signed. |
67 |
</p> |
68 |
<p> |
69 |
Furthermore, a remote attacker might employ a specially crafted X.509 |
70 |
certificate, containing a NUL character in the Common Name field to |
71 |
conduct man-in-the-middle attacks on SSL connections made using |
72 |
Fetchmail. |
73 |
</p> |
74 |
</impact> |
75 |
<workaround> |
76 |
<p> |
77 |
There is no known workaround at this time. |
78 |
</p> |
79 |
</workaround> |
80 |
<resolution> |
81 |
<p> |
82 |
All Fetchmail users should upgrade to the latest version: |
83 |
</p> |
84 |
<code> |
85 |
# emerge --sync |
86 |
# emerge --ask --oneshot --verbose ">=net-mail/fetchmail-6.3.14"</code> |
87 |
