RC4 encryption/decryption functions.

<impact type="normal">
<p>
A remote attacker could entice a user to process an XML file using a
specially crafted XSLT stylesheet in an application linked against
libxslt, possibly leading to the execution of arbitrary code with the
privileges of the user running the application.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All libxslt users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-libs/libxslt-1.1.24-r1&quot;</code>
