Summary: Security Issue Related to netty-codec
Key: ZOOKEEPER-4413
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-4413
Project: ZooKeeper
Issue Type: Improvement
Affects Versions: 3.7.0
Reporter: Daniel Ma
Our security scan detected CVE-2021-37136 and CVE-2021-37137 in
netty.io_netty_codec:
{code:java}
CVE-2021-37136
The Bzip2 decompression decoder function doesn\'t allow setting size
restrictions on the decompressed output data (which affects the allocation size
used during decompression). All users of Bzip2Decoder are affected. The
malicious input can trigger an OOME and so a DoS attack
CVE-2021-37137
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.
fixed in 4.1.68{code}
