Hi,
The following vulnerabilities were published for netty.
CVE-2021-37136[0]:
| 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
https://github.com/netty/netty/security/advisories/GHSA-grg4-wf29-r9vv
Fixed by: https://github.com/netty/netty/commit/41d3d61a61608f2223bb364955ab2045dd5e4020 (netty-4.1.68.Final)
CVE-2021-37137[1]:
| 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.
