|
<p>Multiple vulnerabilities have been found in nginx:</p>
|
|
|
|
<ul>
|
|
<li>The TLS protocol does not properly handle session renegotiation
|
|
requests (CVE-2009-3555).
|
|
</li>
|
|
<li>The "ngx_http_process_request_headers()" function in ngx_http_parse.c
|
|
could cause a NULL pointer dereference (CVE-2009-3896).
|
|
</li>
|
|
<li>nginx does not properly sanitize user input for the the WebDAV COPY
|
|
or MOVE methods (CVE-2009-3898).
|
|
</li>
|
|
<li>The "ngx_resolver_copy()" function in ngx_resolver.c contains a
|
|
boundary error which could cause a heap-based buffer overflow
|
|
(CVE-2011-4315).
|
|
</li>
|
|
<li>nginx does not properly parse HTTP header responses which could
|
|
expose sensitive information (CVE-2012-1180).
|
|
</li>
|
|
</ul>
|
|
</description>
|
|
<impact type="high">
|
|
<p>A remote attacker could possibly execute arbitrary code with the
|
|
privileges of the nginx process, cause a Denial of Service condition,
|
|
create or overwrite arbitrary files, or obtain sensitive information.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>There is no known workaround at this time.</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>All nginx users should upgrade to the latest version:</p>
|
|
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/nginx-1.0.14"
|
|
</code>

|
