<define-tag description>LTS security update</define-tag>
<define-tag moreinfo>
<p>Several vulnerabilities were discovered in Netty, a Java NIO
client/server socket framework:</p>
<ul>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2014-0193">CVE-2014-0193</a>
<p>WebSocket08FrameDecoder allows remote attackers to cause a denial
of service (memory consumption) via a TextWebSocketFrame followed
by a long stream of ContinuationWebSocketFrames.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2014-3488">CVE-2014-3488</a>
<p>The SslHandler allows remote attackers to cause a denial of
service (infinite loop and CPU consumption) via a crafted
SSLv2Hello message.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-16869">CVE-2019-16869</a>
<p>Netty mishandles whitespace before the colon in HTTP headers (such
as a "Transfer-Encoding : chunked" line), which leads to HTTP
request smuggling.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-20444">CVE-2019-20444</a>
<p>HttpObjectDecoder.java allows an HTTP header that lacks a colon,
which might be interpreted as a separate header with an incorrect
syntax, or might be interpreted as an "invalid fold."</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2019-20445">CVE-2019-20445</a>
<p>HttpObjectDecoder.java allows a Content-Length header to be
accompanied by a second Content-Length header, or by a
Transfer-Encoding header.</p></li>
<li><a href="https://security-tracker.debian.org/tracker/CVE-2020-7238">CVE-2020-7238</a>
<p>Netty allows HTTP Request Smuggling because it mishandles
Transfer-Encoding whitespace (such as a
[space]Transfer-Encoding:chunked line) and a later Content-Length
header.</p></li>
</ul>
<p>For Debian 8 <q>Jessie</q>, these problems have been fixed in version
3.9.0.Final-1+deb8u1.</p>
<p>We recommend that you upgrade your netty-3.9 packages.</p>
