| <background> |
| <p>GnuTLS is an Open Source implementation of the TLS 1.2 and SSL 3.0 |
| protocols. |
| </p> |
| </background> |
| <description> |
| <p>Multiple vulnerabilities have been found in GnuTLS:</p> |
| |
| <ul> |
| <li>An error in libgnutls does not properly sanitize "\0" characters from |
| certificate fields (CVE-2009-2730). |
| </li> |
| <li>An error in the TLS and SSL protocols mistreats renegotiation |
| handshakes (CVE-2009-3555). |
| </li> |
| <li>A boundary error in the "gnutls_session_get_data()" function in |
| gnutls_session.c could cause a buffer overflow (CVE-2011-4128). |
| </li> |
| <li>An error in the "_gnutls_ciphertext2compressed()" function in |
| gnutls_cipher.c could cause memory corruption (CVE-2012-1573). |
| </li> |
| </ul> |
| </description> |
| <impact type="normal"> |
| <p>A remote attacker could perform man-in-the-middle attacks to spoof |
| arbitrary SSL servers or cause a Denial of Service condition in |
| applications linked against GnuTLS. |
| </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-2.12.18" |
| </code> |
