<title>OpenSSL: Multiple vulnerabilities</title> |
| 22 |
<synopsis> |
| 23 |
Multiple vulnerabilities in OpenSSL might allow remote attackers to conduct |
| 24 |
multiple attacks, including the injection of arbitrary data into encrypted |
| 25 |
byte streams. |

OpenSSL is an Open Source toolkit implementing the Secure Sockets Layer |
| 43 |
(SSL v2/v3) and Transport Layer Security (TLS v1) as well as a general |
| 44 |
purpose cryptography library. |

Multiple vulnerabilities have been reported in OpenSSL: |
| 50 |
</p> |
| 51 |
<ul> |
| 52 |
<li>Marsh Ray of PhoneFactor and Martin Rex of SAP independently |
| 53 |
reported that the TLS protocol does not properly handle session |
| 54 |
renegotiation requests (CVE-2009-3555).</li> |
| 55 |
<li>The MD2 hash algorithm |
| 56 |
is no longer considered to be cryptographically strong, as demonstrated |
| 57 |
by Dan Kaminsky. Certificates using this algorithm are no longer |
| 58 |
accepted (CVE-2009-2409).</li> |
| 59 |
<li>Daniel Mentz and Robin Seggelmann |
| 60 |
reported the following vulnerabilities related to DTLS: A |
| 61 |
use-after-free flaw (CVE-2009-1379) and a NULL pointer dereference |
| 62 |
(CVE-2009-1387) in the dtls1_retrieve_buffered_fragment() function in |
| 63 |
src/d1_both.c, multiple memory leaks in the |
| 64 |
dtls1_process_out_of_seq_message() function in src/d1_both.c |
| 65 |
(CVE-2009-1378), and a processing error related to a large amount of |
| 66 |
DTLS records with a future epoch in the dtls1_buffer_record() function |
| 67 |
in ssl/d1_pkt.c (CVE-2009-1377).</li> |
| 68 |
</ul> |

<impact type="normal"> |
| 71 |
<p> |
| 72 |
A remote unauthenticated attacker, acting as a Man in the Middle, could |
| 73 |
inject arbitrary plain text into a TLS session, possibly leading to the |
| 74 |
ability to send requests as if authenticated as the victim. A remote |
| 75 |
attacker could furthermore send specially crafted DTLS packages to a |
| 76 |
service using OpenSSL for DTLS support, possibly resulting in a Denial |
| 77 |
of Service. Also, a remote attacker might be able to create rouge |
| 78 |
certificates, facilitated by a MD2 collision. NOTE: The amount of |
| 79 |
computation needed for this attack is still very large. |
| 80 |

<workaround> |
| 83 |
<p> |
| 84 |
There is no known workaround at this time. |

| 87 |
<resolution> |
| 88 |
<p> |
| 89 |
All OpenSSL users should upgrade to the latest version: |
| 90 |
</p> |
| 91 |
<code> |
| 92 |
# emerge --sync |
| 93 |
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8l-r2"</code> |
| 94 |
