<description>
|
|
<p>
|
|
The read_multipart function of the CGI library shipped with Ruby
|
|
(cgi.rb) does not properly check boundaries in MIME multipart content.
|
|
This is a different issue than GLSA 200611-12.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
The vulnerability can be exploited by sending the cgi.rb library a
|
|
crafted HTTP request with multipart MIME encoding that contains a
|
|
malformed MIME boundary specifier. Successful exploitation of the
|
|
vulnerability causes the library to go into an infinite loop.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Ruby users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-lang/ruby-1.8.5_p2"</code>
|
