Description Arun Babu Neelicattu 2014-06-11 08:41:35 UTC 
It was discovered that when handling specifically crafted SSL packets, the SslHandler implementation in Netty entered an infinite loop. An unauthenticated remote attacker could use this flaw to trigger a denial of service by CPU exhaustion.

Affects: 3.9.0, 3.9.1
