| <p>Multiple vulnerabilities have been discovered in GnuTLS. Please review |
| the CVE identifiers referenced below for details. |
| </p> |
| </description> |
| <impact type="normal"> |
| <p>An attacker could perform man-in-the-middle attacks to spoof arbitrary |
| SSL servers via a crafted certificate issued by a legitimate |
| Certification Authority or to inject an arbitrary amount of chosen |
| plaintext into the beginning of the application protocol stream, allowing |
| for further exploitation. |
| </p> |
| </impact> |
| <workaround> |
| <p>There is no known workaround at this time.</p> |
| </workaround> |
| <resolution> |
| <p>All GnuTLS users should upgrade to the latest version:</p> |
| |
| <code> |
| # emerge --sync |
| # emerge --ask --oneshot --verbose ">=net-libs/gnutls-2.10.0" |
| </code> |
| |
| <p>NOTE: This is a legacy GLSA. Updates for all affected architectures are |
| available since August 6, 2010. It is likely that your system is already |
| no longer affected by this issue. |
