CVE-2020-11612: Buffer Overflow

Published Jan 31, 2020
·
Updated

A flaw was found in Netty in the way it handles the amount of data it compresses and decompresses. The Compression/Decompression codecs should enforce memory allocation size limits to avoid an Out of Memory Error (OOME) or exhaustion of the memory pool.

A vulnerability was found in Netty in the way it handles the amount of data it compress and decompress. Compression/Decompression Codecs should enforce memory allocation size limits to avoid OOME or exhaust the memory pool.

Reference: https://github.com/netty/netty/pull/9924

— Red Hat

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.
