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