| OpenSSL is an implementation of the Secure Socket Layer and Transport |
| Layer Security protocols. |

| <description> |
| <p> |
| Moritz Jodeit reported an off-by-one error in the |
| SSL_get_shared_ciphers() function, resulting from an incomplete fix of |
| CVE-2006-3738. A flaw has also been reported in the |
| BN_from_montgomery() function in crypto/bn/bn_mont.c when performing |
| Montgomery multiplication. |
| </p> |
| </description> |
| <impact type="high"> |
| <p> |
| A remote attacker sending a specially crafted packet to an application |
| relying on OpenSSL could possibly execute arbitrary code with the |
| privileges of the user running the application. A local attacker could |
| perform a side channel attack to retrieve the RSA private keys. |
| </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-0.9.8e-r3"</code> |
| </resolution> |
