The remote host is missing an update for the 'netty-3.9'
package(s) announced via the DLA-2110-1 advisory.
Vulnerability Insight:
Several vulnerabilities were discovered in Netty, a Java NIO
client/server socket framework:
CVE-2014-0193
WebSocket08FrameDecoder allows remote attackers to cause a denial
of service (memory consumption) via a TextWebSocketFrame followed
by a long stream of ContinuationWebSocketFrames.
CVE-2014-3488
The SslHandler allows remote attackers to cause a denial of
service (infinite loop and CPU consumption) via a crafted
SSLv2Hello message.
CVE-2019-16869
Netty mishandles whitespace before the colon in HTTP headers (such
as a 'Transfer-Encoding : chunked' line), which leads to HTTP
request smuggling.
CVE-2019-20444
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.'
CVE-2019-20445
HttpObjectDecoder.java allows a Content-Length header to be
accompanied by a second Content-Length header, or by a
Transfer-Encoding header.
CVE-2020-7238
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.
Affected Software/OS:
'netty-3.9' package(s) on Debian Linux.
Solution:
For Debian 8 'Jessie', these problems have been fixed in version
3.9.0.Final-1+deb8u1.
We recommend that you upgrade your netty-3.9 packages.
