Advisory Weakness Curation

Denial of Service in Netty The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

Improper Restriction of Operations within the Bounds of a Memory Buffer This advisory has been marked as a false positive.

Improper Restriction of Operations within the Bounds of a Memory Buffer The `ZlibDecoders` in Netty contains an unbounded memory allocation while decoding a `ZlibEncoded` byte stream. An attacker could send a large `ZlibEncoded` byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

Uncontrolled Resource Consumption The ZlibDecoders in Netty allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.

Allocation of Resources Without Limits or Throttling The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
