<impact type="normal">
|
|
<p>A remote attacker can utilize multiple vectors to cause Denial of
|
|
Service or Information Disclosure.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All OpenSSL 1.0.1 users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-1.0.1l-r1"
|
|
</code>
|
|
|
|
<p>All OpenSSL 0.9.8 users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=dev-libs/openssl-0.9.8z_p5-r1"
|
|
</code>
|
|
|
|
<p>Packages which depend on the OpenSSL library need to be restarted for
|
|
the upgrade to take effect. Some packages may need to be recompiled.
|
|
Tools such as revdep-rebuild may assist in identifying some of these
|
|
packages.
