<description>
|
|
<p>
|
|
w3m in -dump or -backend mode does not correctly handle printf() format
|
|
string specifiers in the Common Name (CN) field of an X.509 SSL
|
|
certificate.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
An attacker could entice a user to visit a malicious website that would
|
|
load a specially crafted X.509 SSL certificate containing "%n" or other
|
|
format string specifiers, possibly resulting in the execution of
|
|
arbitrary code with the rights of the user running w3m.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All w3m users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-client/w3m-0.5.1-r4"</code>
