Red Hat JBoss EAP: CVE-2021-37136: Uncontrolled Resource Consumption

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. A flaw was found in Netty's netty-codec due to size restrictions for decompressed data in the Bzip2Decoder. By sending a specially-crafted input, a remote attacker could cause a denial of service.
