| Doc Text: |
A flaw was found in Netty, a network application framework. A remote attacker could exploit a vulnerability in the SPDY header decoding process. By sending a specially crafted, small compressed header block, the attacker can cause it to expand significantly during decompression, leading to excessive CPU usage and memory allocation. This can result in a denial of service (DoS) due to resource exhaustion.
