-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Package : netty-3.9 Version : 3.9.0.Final-1+deb8u1 CVE ID : CVE-2014-0193 CVE-2014-3488 CVE-2019-16869 CVE-2019-20444 CVE-2019-20445 CVE-2020-7238 Debian Bug : 746639 941266 950966 950967
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. 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.
