<description>

<p>
|
|
Mike Wiacek of the Google Security Team reported a buffer overflow in
|
|
the ARC2 module when processing a large ARC2 key length.

|
<impact type="normal">
|
|
<p>
|
|
A remote attacker could entice a user or automated system to decrypt an
|
|
ARC2 stream in an application using PyCrypto, possibly resulting in the
|
|
execution of arbitrary code or a Denial of Service.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All PyCrypto users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-python/pycrypto-2.0.1-r8"</code>
