David Kierznowski reported that the redirect implementation accepts
|
|
arbitrary Location values when CURLOPT_FOLLOWLOCATION is enabled.

<impact type="normal">
|
|
<p>
|
|
A remote attacker could possibly exploit this vulnerability to make
|
|
remote HTTP servers trigger arbitrary requests to intranet servers and
|
|
read or overwrite arbitrary files via a redirect to a file: URL, or, if
|
|
the libssh2 USE flag is enabled, execute arbitrary commands via a
|
|
redirect to an scp: URL.
|
|
</p>
|

</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All cURL users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.19.4"</code>
