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

| <description> |
| <p> |
| Ossi Herrala and Jukka Taimisto of Codenomicon discovered two |
| vulnerabilities: |
| </p> |
| <ul> |
| <li> |
| A double free() call in the TLS server name extension (CVE-2008-0891). |
| </li> |
| <li> |
| The OpenSSL client code does not properly handle servers that omit the |
| Server Key Exchange message in the TLS handshake (CVE-2008-1672). |
| </li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p> |
| A remote attacker could connect to a vulnerable server, or entice a |
| daemon to connect to a malicious server, causing a Denial of Service of |
| the daemon in both cases. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| All OpenSSL users should upgrade to the latest version: |
| </p> |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8g-r2"</code> |
| </resolution> |
