Description Guilherme de Almeida Suckevicz 2021-09-14 14:41:31 UTC 
The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk.

Comment 1 Jonathan Christison 2021-09-14 17:04:03 UTC 
Marking Red Hat AMQ Broker 7 as having a low impact, this is because although a vulnerable version of netty is used it does not use Snappy (aka. Zippy) compression/decompression.
Comment 3 Patrick Del Bello 2021-09-16 13:44:49 UTC 
Marking Fuse 6 as OOSS and adjusting Fuse 7 to Low Impact. Netty-codec vulnerable version is present but no use of Snappy compression/decompression.
Comment 5 juneau 2021-09-16 15:45:28 UTC 
Marking c.r.c|Insights|MAS affected/ooss. Vulnerable code is present but appears unused.
Comment 6 Yadnyawalk Tale 2021-09-21 13:18:22 UTC 
Reducing Satellite's severity to Low as flaw doesn't affect product directly in code as it does not make use of netty-codec's SnappyFrameDecoder.
Comment 10 Jonathan Christison 2021-10-08 15:32:02 UTC 
Marking Red Hat AMQ Streams, Red Hat Integration Camel K, Red Hat Integration Camel Quarkus as having a low impact, this is because a vulnerable version of netty is distributed in these products and used but the vulnerable Snappy (aka Zippy) decoder is not used.
Comment 12 Jonathan Christison 2021-10-08 15:55:02 UTC 
Marking Red Hat Service Registry 1 & 2 as having a low impact, this is because a vulnerable version of netty is distributed in these products and used but the vulnerable Snappy (aka Zippy) decoder is not used.
Comment 15 Hardik Vyas 2021-10-08 17:02:29 UTC 
Upstream commit: https://github.com/netty/netty/commit/6da4956b31023ae967451e1d94ff51a746a9194f
Comment 17 Jonathan Christison 2021-10-12 15:36:36 UTC 
Marking Quarkus as having a low impact, this is because a vulnerable version of netty is distributed in these products and used but the vulnerable Snappy (aka Zippy) decoder is not used.
