GNU Wget is a free software package for retrieving files using HTTP,
|
|
HTTPS and FTP, the most widely-used Internet protocols.

|
|
The vendor reported that Wget does not properly handle Common Name (CN)
|
|
fields in X.509 certificates that contain an ASCII NUL (\0) character.
|
|
Specifically, the processing of such fields is stopped at the first
|
|
occurrence of a NUL character. This type of vulnerability was recently
|
|
discovered by Dan Kaminsky and Moxie Marlinspike.

<impact type="normal">
|
|
<p>
|
|
A remote attacker might employ a specially crafted X.509 certificate,
|
|
containing a NUL character in the Common Name field to conduct
|
|
man-in-the-middle attacks on SSL connections made using Wget.
|

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Wget users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/wget-1.12"</code>
