when decrypting using ARC2.

PyCrypto is the Python Cryptography Toolkit.
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">
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.
There is no known workaround at this time.
All PyCrypto users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=dev-python/pycrypto-2.0.1-r8&quot;</code>
