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

<description>
|
||
|
|
<p>It was discovered that Wget was unsafely trusting server-provided
|
||
|
|
filenames. This allowed attackers to overwrite or create files on the
|
||
|
|
user's system by sending a redirect from the expected URL to another URL
|
||
|
|
specifying the targeted file.

||
|

|
<impact type="normal">
|
||
|
|
<p>An unauthenticated remote attacker may be able to create or overwrite
|
||
|
|
local files by enticing the user to open an attacker controlled URL,
|
||
|
|
possibly leading to execution of arbitrary code.

|

<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-r2"
|
||
|
|
</code>
