| <title>OpenSSL: Remote execution of arbitrary code</title> |
| <synopsis> |
| OpenSSL contains a vulnerability allowing execution of arbitrary code or a |
| Denial of Service. |

| <affected> |
| <package name="dev-libs/openssl" auto="yes" arch="*"> |

| <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. |
| </p> |
| </background> |
| <description> |
| <p> |
| Andy Polyakov reported a vulnerability in the OpenSSL toolkit, that is |
| caused due to an unspecified off-by-one error within the DTLS |
| implementation. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker could exploit this issue to execute arbitrary code or |
| cause a Denial of Service. Only clients and servers explicitly using |
| DTLS are affected, systems using SSL and TLS are not. |
| </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-0.9.8f"</code> |
| </resolution> |
